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…

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…

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…
