Matroids and isomorphism problems for Bestvina-Brady groups

Yu-Chan Chang, Lorenzo Ruffoni

We propose a factorization of the graph isomorphism problem for Bestvina-Brady groups (BBGs) through matroid theory. In particular, we show that finitely presented BBGs depend on t…

An Ore-type Theorem for Oriented Discrepancy of Hamilton Cycles

Yufei Chang, Yangyang Cheng, Zhilan Wang +2

Oriented discrepancy concerns the existence of prescribed subgraphs whose edges exhibit a substantial imbalance between the two directions. The Hamilton cycle case was first invest…
