Markov chains on Weyl groups from the geometry of the flag variety

Persi Diaconis, Calder Morton-Ferguson

This paper studies a basic Markov chain, the Burnside process, on the space of flags $G / B$ with $G = G L_{n} (F_{q})$ and $B$ its upper triangular matrices. This gives rise to a…

Weight modules and gluing of sheaves on the flag variety

Pablo Boixeda Alvarez, Calder Morton-Ferguson

We study a natural enlargement of the BGG Category O for a semisimple Lie algebra: the category of weight modules with trivial central character and finite-dimensional weight space…

Modular reduction of complex representations of finite reductive groups

Roman Bezrukavnikov, Michael Finkelberg, David Kazhdan +1

The main result describes the Brauer-Nesbitt reduction of unipotent representations of a finite group of Lie type, expressing it as an explicit linear combination of the restrictio…
