Title: The rational homology of smooth, real toric varieties 

Speaker: Alex Suciu, Northeastern University 

Abstract: I will present a formula for computing the Betti numbers of real toric
manifolds, based on a study of cohomology with coefficients in rank one local systems
for various polyhedral products, including real Davis-Januszkiewicz spaces and toric
complexes.  In the case of the Hessenberg varieties, the answer matches a computation
previously done by Henderson and Lehrer, using completely different methods.
