In this paper we prove the existence of a fixed point for multivalued maps satisfying a contraction condition in terms of Q-functions, and via Bianchini-Grandolfi gauge functions, for complete T-0-quasipseudometric spaces. ...

[EN] We study fixed-point free multivalued selfmaps on R as well as continuous fixed-point free selection of multivalued selfmaps on R. We justify necessary conditions in some earlier results and motivate some new interesting ...
[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, ...
