Staircase diagrams and the enumeration of smooth Schubert varietiesArticle

Authors: Edward Richmond ORCID1,2; William Slofstra 3

In this extended abstract, we give a complete description and enumeration of smooth and rationally smooth Schubert varieties in finite type. In particular, we show that rationally smooth Schubert varieties are in bijection with a new combinatorial data structure called staircase diagrams.
