A graph is called weakly perfect if its chromatic number equals its clique number. In this note a new class of weakly perfect graphs is presented and an explicit formula for the chromatic number of such graphs is given.
Classification : 05C17, 05C69, 11A25
Keywords: chromatic number; clique number; weakly perfect graph
