After describing basic concepts such as Radon transforms, the gamma-function, the Fourier transform of distributions, fractional derivatives, and positive definite distributions, Koldobsky describes volume and the Fourier transform, intersection bodies, the Buseman-Petty problem, intersection bodies and Lp-spaces (including Schoenberg's problems on positive definitive functions), Ball's theorem and projections and the Fourier transform.
The complete Gamma-function [Gamma](1 + 1/n) is defined by
where [GAMMA](*) is the Gamma-function and N is the smallest integer satisfying the inequality N > max {-[alpha].
