Key-avoidance for alternating sign matrices av Mathilde Bouvel, Rebecca Smith, Jessica Striker
Publicerad 2025-03-01We initiate a systematic study of key-avoidance on alternating sign matrices (ASMs) defined via pattern-avoidance on an associated permutation called the \emph{key} of an ASM. We enumerate alternating sign matrices whose key avoids a given set of permutation patterns in several instances. We show th...
