摘要

We prove the existence of a polynomial time algorithm to tell whether a graph, with no induced subgraph isomorphic to K-1.3 is well covered. A graph is well-covered if all its maximal independent sets are of the same cardinality. The problem is known to be polynomialy solvable where the input graph is a line graph and it is NP-hard for the larger family of all graphs which do not contain an induced subgraph isomorphic to K-1,K-4.
