Testing the max-flow min-cut property and the replication conjecture

Ahmad Abdi, Tamás Schwarcz

The replication conjecture [Conforti and Cornuéjols, 1993] states that every clutter with the packing property has the MFMC property. If true, this conjecture would have far-reachi…

Fixed-parameter tractability and hardness for Steiner rooted and locally connected orientations

Kristóf Bérczi, Florian Hörsch, András Imolay +1

Finding a Steiner strongly -arc-connected orientation is particularly relevant in network design and reliability, as it guarantees robust communication between a designated set…

Generalizing the Multiple Exchange Property for Matroid Bases

Taihei Oki, Tamás Schwarcz

The multiple exchange property for matroid bases states that for any bases and of a matroid and any subset , there exists a subset $Y\subseteq B\se…

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…

Towards the Proximity Conjecture on Group-Labeled Matroids

Dániel Garamvölgyi, Ryuhei Mizutani, Taihei Oki +2

Consider a matroid whose ground set is equipped with a labeling to an abelian group. A basis of is called -avoiding if the sum of the labels of its elements is not in a…

Matroid products via submodular coupling

Kristóf Bérczi, Boglárka Gehér, András Imolay +3

The study of matroid products traces back to the 1970s, when Lovász and Mason studied the existence of various types of matroid products with different strengths. Among these, the…
