SPECIAL COLLOQUIUM
TITLE: A convex structure on representations of C*-algebras
SPEAKER: Scott Atkinson, Vanderbilt University
TIME: 3:30 PM-4:30 PM
ROOM: Ayres 405
Given a separable unital C*-algebra A, we associate to it an invariant built out of representations of A in a II_1-factor von Neumann algebra (an infinite-dimensional analog of a matrix algebra) modulo appropriate symmetries. This invariant is endowed with a natural convex structure and can be perceived as a non-commutative generalization of the simplex of Borel probability measures on a compact Hausdorff space.

After sketching the construction of this invariant, we will discuss the connections (and disconnections) between certain convex geometric concepts and operator algebraic notions. For instance, we can ask the following questions. How can we algebraically describe an extreme point or a face? What is the geometric interpretation of an ideal? How do properties such as amenability manifest themselves in this invariant? We will discuss these questions along with some purely operator algebraic insights stemming from this invariant, and we will conclude with open problems and future directions.


Thursday, 1/10

MATH BIOLOGY SEMINAR
TITLE: Mathematical Biology Seminar – Organizational Lunch Meeting
TIME: 11:45 AM-12:30 PM
