摘要:For a connected graph G, a spanning tree T of G is called a homeomorphically irreducible spanning tree (HIST) if T has no vertices of degree 2. Albertson et al. proved that it is NP-complete to decide whether a graph contains a HIST. In this talk, we will present some (spectral) conditions that guarantee the existence of a HIST in a connected graph.
