  text: An asymptotic formula is established for the number of rational points of
    bounded anticanonical height which lie on a certain Zariskiopen subset of an arbitrary
    smooth biquadratic hypersurface in sufficiently many variables. The proof uses
    the Hardy–Littlewood circle method.

  text: In this article we define an algebraic vertex of a generalized polyhedron
    and show that the set of algebraic vertices is the smallest set of points needed
    to define the polyhedron. We prove that the indicator function of a generalized
    polytope P is a linear combination of indicator functions of simplices whose vertices
    are algebraic vertices of P. We also show that the indicator function of any generalized
    polyhedron is a linear combination, with integer coefficients, of indicator functions
    of cones with apices at algebraic vertices and line-cones. The concept of an algebraic
    vertex is closely related to the Fourier–Laplace transform. We show that a point
    v is an algebraic vertex of a generalized polyhedron P if and only if the tangent
    cone of P, at v, has non-zero Fourier–Laplace transform.
