$l^2$ betti numbers and s-malleable deformations

abstract:

a major theme in the study of von neumann algebras is to investigate which structural aspects of the group extend to its von neumann algebra. i present recent progress made by dan hoff, ben hayes, thomas sinclair and myself in the case where the group has positive first $l^2$ betti number. i will also expand on our analysis of s-malleable deformations and their relation to cocylces which forms the foundation of our work.
