Bridge graphs and Deodhar parametrizations for positroid varieties

Rachel Karpman

A parametrization of a positroid variety $Π$ of dimension $d$ is a regular map $(C^{\times})^{d} \to Π$ which is birational onto a dense subset of $Π$ . There are s…

A superdimension formula for gl(m|n) modules

Michael Chmutov, Rachel Karpman, Shifra Reif

We give a formula for the superdimension of a finite-dimensional simple gl(m|n)-module using the Su-Zhang character formula. As a corollary, we obtain a simple algebraic proof of a…
