Rank-Metric Codes and $q$-Polymatroids. (arXiv:1803.10844v1 [cs.IT])

We study some algebraic and combinatorial invariants of rank-metric codes, specifically generalized weights. We introduce $q$-polymatroids, the $q$-analogue of polymatroids, and develop their basic properties. We show that rank-metric codes give rise to $q$-polymatroids, and that several of their structural properties are captured by the associated combinatorial object.
