Cohomology of cluster varieties

Abstract: I will talk about joint work with David Speyer where we
study the singular cohomology of cluster varieties, and in particular about the "curious Lefschetz duality" that these cohomology rings satisfy.  There are relations to the study of higher extension groups of Verma modules in the principal block of Category O, and to the study of rational q,t-Catalan polynomials.
