Frames and Functional Analysis

Remembering Pete

Peter G. Casazza (1945–2025) spent nearly four decades at the University of Missouri, where his work helped establish frame theory as one of the most active areas of mathematical research. He earned his Ph.D. from the University of Iowa in 1972 and, after appointments at the University of Alabama–Huntsville, joined the University of Missouri in 1983, where he remained until his retirement in 2021.

A Curators’ Distinguished Professor and director of the Frame Research Center, Pete delivered more than 400 invited lectures in 35 countries and mentored generations of mathematicians, many alongside his wife and longtime collaborator, Janet Tremain. Over the years, his work brought him into contact with mathematicians from around the world, leading to numerous collaborations and lasting friendships.

The Pete Casazza Memorial Workshop, taking place December 4–6 at the University of Missouri, brings together his colleagues, collaborators, former students, and friends to remember Pete and celebrate his contributions to mathematics. The workshop will feature research talks in areas connected to his work, as well as time to share memories and reconnect with one another.
