Some Matroids Related to Sum-Rank Metric Codes.
2019
The notion of sum-matroid, which generalizes the notions of both matroid and $q$-matroid, is introduced. Generalized weights are defined for sum-matroids and we prove a Wei-type duality theorem involving generalized weights of a sum-matroid and its dual. We further establish a connection between the theory of sum-rank metric codes and that of sum-matroids by associating a sum-matroid to a given sum-rank metric code. It is shown that the results on sum-matroids recover those of sum-rank metric codes studied by Mart{i}nez-Pe{n}as.
