Abstract:
It is conjectured that all longest cycles in any 2-connected chordal graph have a common vertex, where a chordal graph can be considered as the intersection graphs of a collection of subtrees of a host tree. We prove the case that the host tree has at most two vertices with degree at least three.
This is joint work with Guantao Chen and Shaohui Wang.
