Functions of bounded variation represent an important class of functions. Studying their Fourier transforms is a valuable means of revealing their analytic prop

The aim of this monograph is to give a thorough and self-contained account of functions of (generalized) bounded variation, the methods connected with their stu

This book is aimed at the approximation of set-valued functions with compact sets in an Euclidean space as values. The interest in set-valued functions is rathe

This volume contains the proceedings of the IMU/AMS Special Session on Nonlinear Analysis and Optimization, held from June 16-19, 2014, at the Second Joint Inte

This monograph presents the summability of higher dimensional Fourier series, and generalizes the concept of Lebesgue points. Focusing on Fejér and Cesàro sum
