Ringel Duality for Extended ZigZag Schur Algebra

Alexander Kleshchev, Ilan Weinschelbaum

Extended zigzag Schur algebras are quasi-hereditary algebras which are conjecturally Morita equivalent to RoCK blocks of classical Schur algebras. We prove that extended zigzag Sch…

Good filtrations for generalized Schur algebras

Alexander Kleshchev, Ilan Weinschelbaum

Given a quasi-hereditary superalgebra $A$ , the first author and R. Muth have defined generalized Schur bi-superalgebras $T^{A} (n)$ and proved that these algebras are again quasi-here…

Six variations on a theme: almost planar graphs

Max Lipton, Eoin Mackall, Thomas W. Mattman +4

A graph is apex if it can be made planar by deleting a vertex, that is, $\exists v$ such that $G - v$ is planar. We define the related notions of edge apex, $\exists e$ such that $G-…
