Stable sets for $(P₆,K_{2,3})$-free graphs

The Maximum Stable Set (MS) problem is a well known NP-hard problem. However different graph classes for which MS can be efficiently solved have been detected and the augmenting graph technique seems to be a fruitful tool to this aim. In this paper we apply a recent characterization of minimal augmenting graphs [22] to prove that MS can be solved for $(P₆,K_{2,3})$-free graphs in polynomial time, extending some known results
