DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NYC-NCG/169/
 ">Elliott invariant in a geometric context</a>\nby Valerio Proietti (Unive
 rsity of Oslo) as part of Noncommutative geometry in NYC\n\n\nAbstract\nGi
 ven a class of topological dynamical systems\, we study the associated map
 ping torus from the point of view of foliated spaces. By studying the inte
 raction between the leafwise Dirac operator and the invariant transverse m
 easures\, we reframe in a geometric fashion the Elliott invariant for the 
 crossed product of the dynamical system\, and prove a rigidity result for 
 the mapping torus\, lifting leafwise homotopy equivalences to isomorphism 
 of the noncommutative leaf space. Joint work with Hao Guo and Hang Wang.\n
