Schubert Calculus and Positivity

Schubert calculus is the study of certain intersections of varieties in the flag manifold.  These intersections are /positive/ in the differential-geometric sense, but they also have “positivity properties” in several associated rings, notably equivariant cohomology

On the topology of a small cover associated to a shellable complex

Small covers are real analogues to quasi-toric manifolds: the fixed points under complex conjugation (i.e., the real toric manifold) in a projective toric manifold is a small cover; Buchstaber and Ray showed that every unoriented cobordism class contains a small cover as its representative.   A s
