Title: Torsion invariants in operator algebras and K-theory

Abstract: Determinant-type invariants known as joint torsion may be associated to collections of operators that commute modulo trace ideals.  These have been applied to problems in operator theory, asymptotics of determinants, and the classification of almost normal operators up to almost unitary equivalence.  We will review the construction of these invariants and discuss recent work on their applications.

Refreshments are available at 3:00 PM in SC 313F.

The department colloquia are held every Thursday (excluding holidays) at 3:35 pm in room SC 323 unless otherwise noted. All are invited to attend.
