THEMATIC PROGRAMS 

May 28, 2023  
OverviewThe theme of these lectures will be that there are at least two
quite different ideas of what it means to classify the objects of
a category up to isomorphism. One of these is classification by
invariants with good computational properties, while the other,
surely familiar to regular attendees of the AST series, is the notion
of Borel reducibility. We will examine how they both contrast and
complement each other through the lens of C*algebra theory. For
more details, see Invited speakers1. Caleb Eckhardt, Department of Mathematics, Purdue University 2. Andrew Toms, Department of Mathematics, Purdue University Schedule
