β¦ Synopsis
We prove a general form of a fixed point theorem for mappings from a Riemannian manifold into itself which are obtained as perturbations of a given mapping by means of general operations which in particular include the cases of sum (when a Lie group structure is given on the manifold) and composition. In order to prove our main result we develop a theory of proximal calculus in the setting of Riemannian manifolds.

In this work, we give a metric function on the space of finite measures on a compact metric space, which has some interesting metric properties. As an application, we establish the existence of essential components of the set of fixed points for every upper semicontinuous convex set-valued mapping o
In this paper, we introduce the concept of a Q-function defined on a quasi-metric space which generalizes the notion of a Ο -function and a w-distance. We establish Ekeland-type variational principles in the setting of quasi-metric spaces with a Q-function. We also present an equilibrium version of
