The geometric Littlewood-Richardson (LR) rule is a combinatorial algorithm for computing LR coefficients derived from degenerating the Richardson variety into a union of Schubert varieties in the Grassmannian. Such rules were first given by Vakil and

Staircase diagrams and the enumeration of smooth Schubert varieties

Autor: William Slofstra, Edward Richmond

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 da

International audience; Nitro compounds are known to change reaction rates and kinetic concentration dependence of Brønsted-acid-catalyzed reactions. Yet, no mechanistic model exists to account for these observations. Herein we present an atomistic

Catalytic B(C6F5)3H2O-promoted defluorinative functionalization of tertiary aliphatic fluorides

Autor: Guang Li, Marian Dryzhakov, Joseph Moran, Edward Richmond

Publikováno v: Journal of Fluorine Chemistry. 193:45-51

A B(C 6 F 5 ) 3 H 2 O-catalyzed defluorinative functionalization of tertiary aliphatic fluorides is described that proceeds under benign reaction conditions. The synthetic utility of the method is exemplified through the fast and efficient formation

An equivariant basis for the cohomology of Springer fibers

Autor: Martha Precup, Edward Richmond

Springer fibers are subvarieties of the flag variety that play an important role in combinatorics and geometric representation theory. In this paper, we analyze the equivariant cohomology of Springer fibers for $GL_n(\mathbb{C})$ using results of Kum
