Over the course of the last century, the systematic exploration of the relationship between Fourier analysis and other branches of mathematics has lead to important advances in geometry, number theory, and analysis, stimulated in part by Hurwitz's proof of the isoperimetric inequality using Fourier series.
This unified, self-contained book presents both a broad overview of Fourier analysis and convexity, as well as an intricate look at applications in some specific settings; it will be useful to graduate students and researchers in harmonic analysis, convex geometry, functional analysis, number theory, computer science, and combinatorial analysis. A wide audience will benefit from the careful demonstration of how Fourier analysis is used to distill the essence of many mathematical problems in a natural and elegant way.

Zusammenfassung
During the last century the relationship between Fourier analysis and other areas of mathematics has been systematically explored resulting in important advances in geometry, number theory, and analysis. The expository articles in this unified, self-contained volume explore those advances and connections. Specific topics covered included: geometric properties of convex bodies, Radon transforms, geometry of numbers, tilings, irregularities in distributions, and restriction problems for the Fourier transform. Graduate students and researchers in harmonic analysis, convex geometry, and functional analysis will benefit from the book’s careful demonstration of how Fourier analysis is used to distill the essence of many mathematical problems in a natural and elegant way.
