Full Story

Professor Emeritus Alberto Torchinsky has just published a new book on the classical topic of the Riemann integral. The idea for the text arose, curiously, out of conversations related to signal processing with his son IU alum Darius (BS Math and Physics ’99). Historically, the development of the theory of integration went through many phases, with Riemann’s more concrete version appearing before Lebesgue’s more abstract version. This monograph, published in the prestigious Springer Lecture Notes series, embarks on an exploration rooted in Riemann’s original viewpoint.
