The Operator Theory Seminar meets

Wednesdays, 1:30p - 2:45p, via ZOOM

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!

Questions about the seminar and requests to be added to the mailing list can be directed to Carl Cowen:   ccowen "at" iupui "dot" edu
