A q-analogue of delta-matroids and related concepts

Michela Ceria, Trygve Johnsen, Relinde Jurrius

Published 2024-06-21Version 1

We define and study q-delta-matroids, and q-g-matroids. These objects are analogues, for finite-dimensional vector spaces over finite fields, of delta-matroids and g-matroids arising from finite sets. We compare axiomatic descriptions with definitions by means of strong maps of q-matroids.
