He published over Stein phenomena”) in which they constructed fifty research articles, uniformly bounded nonunitary representations Photo taken by Ken Gross. among which were sem- of a semisimple Lie group G and showed that Ray Kunze inal results of primary convolution by an Lp function is a bounded importance in representation theory and harmonic operator on L2(G) for all 1 ≤ p < 2. There is no analysis. As well, his classic textbook on linear analogue in the classical theory, as convolution algebra, co-authored with Kenneth Hoffman, was by an Lp function on Rn is bounded only when translated into many languages and used around p = 1.
