for zoom info, email ccowen "at" iupui "dot" edu

Fall Semester, starting 9/2/20

The operator theory seminar is a working seminar
for students and others who want
to learn about this kind of mathematics as well as a forum for participants
to present new work, of their own or the work of others, or to read together
related function theory or functional analysis.
All are welcome!
