Our results extend, improve, and generaliz...
 作者：Josefa Marín , Salvador Romaguera , Pedro Tirado 来源：[J].Fixed Point Theory and Applications(IF 1.866), 2011, Vol.2011 (1), pp.1-9Springer 摘要：Abstract(#br)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.

By using the nonlinear alternative of Leray-Schauder type for multivalued maps due to O’Regan and properties of the α -resolvent operator combined with approximation techniques, we derive a new set of sufficient conditions for the approximate controllability of fracti...
