Seminar za računarstvo i primenjenu matematiku, 4. jun 2024.

Naredni sastanak Seminara biće održan u utorak, 4. juna 2024. u sali 301f Matematičkog instituta SANU sa početkom u 14 časova. U pitanju je predavanje iz ciklusa „Lekcije Ruđera Boškovića“ na MI SANU.

Predavač: Adam Skalski, Mathematical Institute Polish Academy of Sciences

Naslov predavanja: (MAXIMAL) HAAGERUP PROPERTY FOR GROUPS AND OPERATOR ALGEBRAS

Apstrakt: The talk will be divided into two parts:  the first will have an introductory character: we will discuss how one associates to a discrete group a von Neumann algebra, and explain how the approximation properties for a discrete group (such as say amenability or the Haagerup property) can be reflected via the properties of the algebra in question. We will also spend some time explaining the origins and motivations behind the study of approximation properties of operator algebras, focusing on the Haagerup property.  

In the second part of the talk we will present some results regarding concrete examples of maximal Haagerup subgroups and von Neumann subalgebras, obtained in joint work with Yongle Jiang.
