From Trees to Tripods: Proof of for Artin groups with -type spherical parabolics
Nima Hoda, Jingyin Huang
We reduce the -conjecture for all Artin groups with tree Coxeter diagrams to properties of Artin groups with tripod-shaped Coxeter diagrams. Combining this reduction theore…
Bestvina metric and tree reduction for -conjecture
Jingyin Huang
We reduce the -conjecture for all Artin groups to properties of Artin groups whose Coxeter diagrams are trees, from which we deduce new classes of Artin groups satisfying t…
On graphs which have locally complete 2-edge-colourings and their relationship to proper circular-arc graphs
Jørgen Bang-Jensen, Jing Huang
A 2-edge-coloured graph is called {\bf locally complete} if for each vertex , the vertices adjacent to through edges of the same colour induce a complete subgraph in …
Good orientations of 2T-graphs
J. Bang-Jensen, S. Bessy, J. Huang +1
In this paper we study graphs which admit acyclic orientations that contain a pair of arc-disjoint out-branching and in-branching (such an orientation is called good) and we focus…
