Crossed Product Splitting of Intermediate Operator Algebras via 2-Cocycles

Explore a comprehensive lecture on the crossed product splitting of intermediate operator algebras using 2-cocycles. Delve into a new complete description theorem that unifies discrete Galois correspondence results and crossed product splitting results. Examine the application of this theorem to obtain a Galois-type result for Bisch-Haagerup type inclusions arising from isometrically shift-absorbing actions of compact-by-discrete groups. Learn about the speaker's research, based on the preprint arxiv:2406.00304, and gain insights into advanced topics in operator algebra theory during this 1-hour and 4-minute presentation from the BIMSA organization.
