Here are the details:

Where: University of Trieste (main campus), Via Valerio 12/1, H2bis building, 3rd floor, room 334 (seminar room).

Title: The Motzkin subproduct system

Abstract: Subproduct systems, defined by Shalit and Solel in 2009, provide a framework for constructing interesting C$^$-algebras. More recently, Habbestad and Neshveyev introduced Temperley-Lieb subproduct systems. We extend their construction using Motzkin algebras and their Jones-Wenzl idempotents. We show that the resulting Toeplitz and Cuntz-Pimsner C$^$-algebra are universal, that is, it can be defined in terms of generators and relations, and we investigate aspects of its representation theory. This is joint work with Simone Del Vecchio and Stefano Rossi (Univ. di Bari).

Everyone is welcome!

Best regards,
Arnaud
