In this paper we prove the existence of fixed points for multifunctions verifying the property of weakly uniformly strict p-contraction. Then, as a corollary, we deduce a result on the existence of contractive fixed points for single-valued functions not necessarily with complete graph, which strictly contains a result due to Keeler and Meir.

Abstract
In this paper we prove the existence of fixed points for multifunctions verifying the property of weakly uniformly strict p-contraction. Then, as a corollary, we deduce a result on the existence of contractive fixed points for single-valued functions not necessarily with complete graph, which strictly contains a result due to Keeler and Meir.File in questo prodotto:
