Convergent sequences of combinatorial submodular setfunctions
Kristóf Bérczi, Márton Borbényi, László Lovász +1
To illustrate that the notion of convergence of submodular function sequences fits reasonably into the limit theory of graphs, we describe several classes of matroids and other sub…

Interaction between skew-representability, tensor products, extension properties, and rank inequalities
Kristóf Bérczi, Boglárka Gehér, András Imolay +3
Skew-representable matroids form a fundamental class in matroid theory, bridging combinatorics and linear algebra. They play an important role in areas such as coding theory, optim…
