Matthew Kennedy, a Professor in the Department of Pure Mathematics, has been awarded the 2025 Ciprian Foias Prize in Operator Theory by the American Mathematical Society (AMS). Kennedy has been honoured for his wide-ranging and innovative work on group C*-algebras, according to the citation.
His paper "An intrinsic characterization of C*-simplicity,” on which the award is based, is the culmination of earlier work in collaboration with Kalantar, Breuillard, and Ozawa. The methods introduced in this work, namely an operator-algebraic theory of boundaries, have subsequently found applications in the study of more general classes of C*-algebras and to dynamical systems.
"I am deeply honored to receive the 2025 Ciprian Foias Prize in Operator Theory," Kennedy says. "I am thankful to all of my collaborators, and especially to my good friend Mehrdad Kalantar."
