Weakly contractive multivalued maps and w-distanceson complete quasi-metric spaces

[EN] We obtain versions of the Boyd and Wong fixed point theorem and of the Matkowski fixed point theorem for multivalued maps and w-distances on complete quasi-metric spaces. Our results generalize, in several directions, some well-known fixed point theorems.The authors acknowledge the support of the Spanish Ministry of Science and Innovation, under grant MTM2009-12872-C02-01.Marín Molina, J.; Romaguera Bonilla, S.; Tirado Peláez, P.
