  text: "Let $\\ell$ be a prime number. We classify the subgroups $G$ of $\\operatorname{Sp}_4(\\mathbb{F}_\\ell)$
    and $\\operatorname{GSp}_4(\\mathbb{F}_\\ell)$ that act irreducibly on $\\mathbb{F}_\\ell^4$,
    but such that every element of $G$ fixes an $\\mathbb{F}_\\ell$-vector subspace
    of dimension 1. We use this classification to prove that the local-global principle
    for isogenies of degree $\\ell$ between abelian surfaces over number fields holds
    in many cases -- in particular, whenever the abelian surface has non-trivial endomorphisms
    and $\\ell$ is large enough with respect to the field of definition. Finally,
    we prove that there exist arbitrarily large primes $\\ell$ for which some abelian
    surface\r\n$A/\\mathbb{Q}$ fails the local-global principle for isogenies of degree
    $\\ell$."

  text: It is known that the Brauer--Manin obstruction to the Hasse principle is vacuous
    for smooth Fano hypersurfaces of dimension at least 3 over any number field. Moreover,
    for such varieties it follows from a general conjecture of Colliot-Thélène that
    the Brauer--Manin obstruction to the Hasse principle should be the only one, so
    that the Hasse principle is expected to hold. Working over the field of rational
    numbers and ordering Fano hypersurfaces of fixed degree and dimension by height,
    we prove that almost every such hypersurface satisfies the Hasse principle provided
    that the dimension is at least 3. This proves a conjecture of Poonen and Voloch
    in every case except for cubic surfaces.

  text: We count primitive lattices of rank d inside Zn as their covolume tends to
    infinity, with respect to certain parameters of such lattices. These parameters
    include, for example, the subspace that a lattice spans, namely its projection
    to the Grassmannian; its homothety class and its equivalence class modulo rescaling
    and rotation, often referred to as a shape. We add to a prior work of Schmidt
    by allowing sets in the spaces of parameters that are general enough to conclude
    the joint equidistribution of these parameters. In addition to the primitive d-lattices
    Λ themselves, we also consider their orthogonal complements in Zn⁠, A1⁠, and show
    that the equidistribution occurs jointly for Λ and A1⁠. Finally, our asymptotic
    formulas for the number of primitive lattices include an explicit bound on the
    error term.

  text: We use a function field version of the Hardy–Littlewood circle method to study
    the locus of free rational curves on an arbitrary smooth projective hypersurface
    of sufficiently low degree. On the one hand this allows us to bound the dimension
    of the singular locus of the moduli space of rational curves on such hypersurfaces
    and, on the other hand, it sheds light on Peyre’s reformulation of the Batyrev–Manin
    conjecture in terms of slopes with respect to the tangent bundle.

  text: We establish effective counting results for lattice points in families of
    domains in real, complex and quaternionic hyperbolic spaces of any dimension.
    The domains we focus on are defined as product sets with respect to an Iwasawa
    decomposition. Several natural diophantine problems can be reduced to counting
    lattice points in such domains. These include equidistribution of the ratio of
    the length of the shortest solution (x,y) to the gcd equation bx−ay=1 relative
    to the length of (a,b), where (a,b) ranges over primitive vectors in a disc whose
    radius increases, the natural analog of this problem in imaginary quadratic number
    fields, as well as equidistribution of integral solutions to the diophantine equation
    defined by an integral Lorentz form in three or more variables. We establish an
    effective rate of convergence for these equidistribution problems, depending on
    the size of the spectral gap associated with a suitable lattice subgroup in the
    isometry group of the relevant hyperbolic space. The main result underlying our
    discussion amounts to establishing effective joint equidistribution for the horospherical
    component and the radial component in the Iwasawa decomposition of lattice elements.

  text: Let P be a nontorsion point on an elliptic curve defined over a number field
    K and consider the sequence {Bn}n∈N of the denominators of x(nP). We prove that
    every term of the sequence of the Bn has a primitive divisor for n greater than
    an effectively computable constant that we will explicitly compute. This constant
    will depend only on the model defining the curve.

  text: 'Let k be a number field and X a smooth, geometrically integral quasi-projective
    variety over k. For any linear algebraic group G over k and any G-torsor g : Z
    → X, we observe that if the étale-Brauer obstruction is the only one for strong
    approximation off a finite set of places S for all twists of Z by elements in
    H^1(k, G), then the étale-Brauer obstruction is the only one for strong approximation
    off a finite set of places S for X. As an application, we show that any homogeneous
    space of the form G/H with G a connected linear algebraic group over k satisfies
    strong approximation off the infinite places with étale-Brauer obstruction, under
    some compactness assumptions when k is totally real. We also prove more refined
    strong approximation results for homogeneous spaces of the form G/H with G semisimple
    simply connected and H finite, using the theory of torsors and descent.'

  text: "We apply a variant of the square-sieve to produce an upper bound for the
    number of rational points of bounded height on a family of surfaces that admit
    a fibration over P1 whose general fibre is a hyperelliptic curve. The implied
    constant does not depend on the coefficients of the polynomial defining the surface.\r\n"

  text: We establish the Hardy-Littlewood property (à la Borovoi-Rudnick) for Zariski
    open subsets in affine quadrics of the form q(x1,...,xn)=m, where q is a non-degenerate
    integral quadratic form in  n>3 variables and m is a non-zero integer. This gives
    asymptotic formulas for the density of integral points taking coprime polynomial
    values, which is a quantitative version of the arithmetic purity of strong approximation
    property off infinity for affine quadrics.

  text: "We determine an asymptotic formula for the number of integral points of\r\nbounded
    height on a certain toric variety, which is incompatible with part of a\r\npreprint
    by Chambert-Loir and Tschinkel. We provide an alternative\r\ninterpretation of
    the asymptotic formula we get. To do so, we construct an\r\nanalogue of Peyre's
    constant $\\alpha$ and describe its relation to a new\r\nobstruction to the Zariski
    density of integral points in certain regions of\r\nvarieties."
acknowledgement: "Part of this work was conducted as a guest at the Institut de Mathématiques
  de Jussieu–Paris Rive Gauche invited by Antoine Chambert-Loir and funded by DAAD.\r\nDuring
  this time, I had interesting and fruitful discussions on the interpretation of the
  result for\r\nthe toric variety discussed in Section 3 with Antoine Chambert-Loir.
  I wish to thank him for these\r\nopportunities and for his useful remarks on earlier
  versions of this article. This work was partly\r\nfunded by FWF grant P 32428-N35."

  text: 'Let t : Fp → C be a complex valued function on Fp. A classical problem in
    analytic number theory is bounding the maximum M(t) := max 0≤H<p ∣ 1/√p ∑ 0≤n<H
    t (n) ∣ of the absolute value of the incomplete sums(1/√p)∑0≤n<H t (n). In this
    very general context one of the most important results is the Pólya–Vinogradov
    bound M(t)≤IIˆtII∞ log 3p, where ˆt : Fp → C is the normalized Fourier transform
    of t. In this paper we provide a lower bound for certain incomplete Kloosterman
    sums, namely we prove that for any ε > 0 there exists a large subset of a ∈ F×p
    such that for kl a,1,p : x → e((ax+x) / p) we have M(kla,1,p) ≥ (1−ε/√2π + o(1))
    log log p, as p→∞. Finally, we prove a result on the growth of the moments of
    {M (kla,1,p)}a∈F×p. 2020 Mathematics Subject Classification: 11L03, 11T23 (Primary);

  text: "In this thesis, we study two of the most important questions in Arithmetic
    geometry: that of the existence and density of solutions to Diophantine equations.
    In order for a Diophantine equation to have any solutions over the rational numbers,
    it must have solutions everywhere locally, i.e., over R and over Qp for every
    prime p. The converse, called the Hasse principle, is known to fail in general.
    However, it is still a central question in Arithmetic geometry to determine for
    which varieties the Hasse principle does hold. In this work, we establish the
    Hasse principle for a wide new family of varieties of the form f(t) = NK/Q(x)
    ̸= 0, where f is a polynomial with integer coefficients and NK/Q denotes the norm\r\nform
    associated to a number field K. Our results cover products of arbitrarily many
    linear, quadratic or cubic factors, and generalise an argument of Irving [69],
    which makes use of the beta sieve of Rosser and Iwaniec. We also demonstrate how
    our main sieve results can be applied to treat new cases of a conjecture of Harpaz
    and Wittenberg on locally split values of polynomials over number fields, and
    discuss consequences for rational points in fibrations.\r\nIn the second question,
    about the density of solutions, one defines a height function and seeks to estimate
    asymptotically the number of points of height bounded by B as B → ∞. Traditionally,
    one either counts rational points, or\r\nintegral points with respect to a suitable
    model. However, in this thesis, we study an emerging area of interest in Arithmetic
    geometry known as Campana points, which in some sense interpolate between rational
    and integral points.\r\nMore precisely, we count the number of nonzero integers
    z1, z2, z3 such that gcd(z1, z2, z3) = 1, and z1, z2, z3, z1 + z2 + z3 are all
    squareful and bounded by B. Using the circle method, we obtain an asymptotic formula
    which agrees in\r\nthe power of B and log B with a bold new generalisation of
    Manin’s conjecture to the setting of Campana points, recently formulated by Pieropan,
    Smeets, Tanimoto and Várilly-Alvarado [96]. However, in this thesis we also provide
    the first known counterexamples to leading constant predicted by their conjecture. "

  text: Given a place  ω  of a global function field  K  over a finite field, with
    associated affine function ring  Rω  and completion  Kω , the aim of this paper
    is to give an effective joint equidistribution result for renormalized primitive
    lattice points  (a,b)∈Rω2  in the plane  Kω2 , and for renormalized solutions
    to the gcd equation  ax+by=1 . The main tools are techniques of Goronik and Nevo
    for counting lattice points in well-rounded families of subsets. This gives a
    sharper analog in positive characteristic of a result of Nevo and the first author
    for the equidistribution of the primitive lattice points in  \ZZ2 .
acknowledgement: "The authors warmly thank Amos Nevo for having presented the authors
  to each other during\r\na beautiful conference in Goa in February 2016, where the
  idea of this paper was born. The\r\nfirst author thanks the IHES for two post-doctoral
  years when most of this paper was discussed,\r\nand the Topology team in Orsay for
  financial support at the final stage. The first author was\r\nsupported by the EPRSC
  EP/P026710/1 grant. Finally, we warmly thank the referee for many\r\nvery helpful
  comments that have improved the readability of this paper."

  text: An improved asymptotic formula is established for the number of rational points
    of bounded height on the split smooth del Pezzo surface of degree 5. The proof
    uses the five conic bundle structures on the surface.
acknowledgement: This work was begun while the author was participating in the programme
  on "Diophantine equations" at the Hausdorff Research Institute for Mathematics in
  Bonn in 2009. The hospitality and financial support of the institute is gratefully
  acknowledged. The idea of using conic bundles to study the split del Pezzo surface
  of degree 5 was explained to the author by Professor Salberger. The author is very
  grateful to him for his input into this project and also to Shuntaro Yamagishi for
  many useful comments on an earlier version of this manuscript. While working on
  this paper the author was supported by FWF grant P32428-N35.
