A Polymatroid Approach to Generalized Weights of Rank Metric Codes
Sudhir R. Ghorpade, Trygve Johnsen
We consider the notion of a -polymatroid, due to Shiromoto, and the more general notion of -demi-polymatroid, and show how generalized weights can be defined for them…

Higher weight spectra of Veronese codes
Trygve Johnsen, Hugues Verdure
We study q-ary linear codes C obtained from Veronese surfaces over finite fields. We show how one can find the higher weight spectra of these codes, or equivalently, the weight dis…
