Abstract

The study of torus orbit closures in the (complete) flag variety was initiated by Klyachko and Gelfand–Serganova in the mid-1980s. In this chapter, we present some of the work by Klyachko and Gelfand–Serganova and our recent work on the topology, geometry, and combinatorics of torus orbit closures in the flag variety.
