  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 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: 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."
