  This book is an introduction to the nascent field of Fourier analysis on
polytopes, and cones. There is a rapidly growing number of applications of
these methods, so it is appropriate to invite students, as well as
professionals, to the field. Of the many applications of these techniques, we
have chosen to focus on the following topics:
  (a) Formulations for the Fourier transform of a polytope
  (b) Minkowski and Siegel's theorems in the geometry of numbers
  (c) Tilings and multi-tilings of Euclidean space by translations of a
polytope
  (d) Computing discrete volumes of polytopes, which are combinatorial
approximations to the continuous volume
  (e) Sphere packings, and their packing density
  (f) Iterating the divergence theorem to give new formulations for the Fourier
transform of a polytope, with applications
  (g) Shannon sampling, in several variables
  (h) More topics in the classical geometry of numbers
  We assume familiarity with Linear Algebra, with some Calculus and infinite
series. Throughout, we introduce the topics gently, by giving many examples and
exercises, so that this book is ideally suited for a course, or for self-study.
