On well covered, vertex decomposable and Cohen - Macaulay graphs

LetG= (V, E) be a graph. IfGis a K ̈onig graph or ifGis a graph without3-cycles and 5-cycles, we prove that the following conditions are equivalent: ∆Gis pure shellable,R/I∆is Cohen-Macaulay,Gis an unmixed vertex decomposablegraph andGis well-covered with a perfect atching of K ̈onig typee1, . . . ,...
