Rezensionen

"This book is an introduction to the modern theory of harmonic analysis and differential equations. ... the book would be useful for graduate students as well as for researchers who look for applications in mathematical physics and engineering sciences." (Serge Yu Tikhonov, Mathematical Reviews, February, 2019)
