2023—A twofold commemoration: the 100th birthday of Walsh functions and the 50th anniversary of Professor Joseph Leonard Walsh’s death

Abstract

In 2023, it is 100 years after the introduction of Walsh functions and 50 years after the death of their introducer Joseph Leonard Walsh. This paper is an homage to J. L. Walsh and presents some insights into the development of Walsh and dyadic analysis with applications of Walsh functions in both mathematics and various areas of computing and engineering. The presentation is based on reminiscences of the authors acting in these areas.
