Localization and multiplication of distributions

Ian Richards and Heekyung K. Youn

University of St. Thomas and University of Minnesota

Abstract

Working within classical distribution theory, we develop notions of multiplication and convolution for tempered distributions which are general enough to encompass the classical cases -- such as pointwise multiplication of continuous functions or the convolution of $L^1$ functions -- which most textbook treatments of distribution theory leave out. Pains are taken to develop a theory which satisfies the commutative and associative laws.

Keywords: tempered distributions, localization, multiplication, Fourier transform, partial integration, convolution
