Abstract :
Unmixed bipartite graphs have been characterized by Ravindra and Villarreal independently. Our aim in this paper is to characterize unmixed r-partite graphs under a certain condition, which is a generalization of Villarreal s theorem on bipartite graphs. Also, we give some examples and counterexamples in relevance to this subject.
