On the Weak Relatively Nonexpansive Multivalued Mappings in Banach Spaces
Abstract and Applied Analysis, 2012 In recent years, the definition of relatively nonexpansive multivalued mapping and the definition of weak relatively nonexpansive multivalued mapping have been presented and studied by many authors.

On an Invariant Set in the Heat Conductivity Problem with Time Lag
Abstract and Applied Analysis, 2013 The problems of weak and strong invariance of a constant multivalued mapping with respect to the heat conductivity equation with time lag are studied. Sufficient conditions of weak and strong invariance of a given multivalued mapping are obtained.

Nonholonomic Mapping Principle for Classical Mechanics in Spaces with Curvature and Torsion. New Covariant Conservation Law for Energy-Momentum Tensor [PDF]
, 1997 The lecture explains the geometric basis for the recently-discovered nonholonomic mapping principle which specifies certain laws of nature in spacetimes with curvature and torsion from those in flat spacetime, thus replacing and extending Einstein's ...

Cyclical coincidences of multivalued maps [PDF]
Journal of the Mathematical Society of Japan, 1986 We prove the following result using Brouwer's fixed-point theorem for a simplex. \(\forall\) \(i\in {\mathbb{Z}}_ m\), let \(X_ i\) be a nonempty convex subset of a topological vector space and \(T_ i: X_ i\to 2^{X_{i+1}}\) have nonempty convex values.

Metrizable space of multivalued maps [PDF]
Annales Universitatis Paedagogicae Cracoviensis. Studia Mathematica, 2021 Abstract In this article we define a metrizable space of multivalued maps. We show that the metric defined in this space is closely related to the homotopy of multivalued maps. Moreover, we study properties of this space and give a few practical applications of the new metric.

A Modified Proximal Point Algorithm and Some Convergence Results
Journal of Mathematics, 2021 In this paper, the convergence to minimizers of a convex function of a modified proximal point algorithm involving a single-valued nonexpansive mapping and a multivalued nonexpansive mapping in CAT(0) spaces is studied and a numerical example is given to

Fixed Points for Multivalued Suzuki Type (θ,R)-Contraction Mapping with Applications
Journal of Function Spaces, 2019 In this paper, we will introduce the concept of Suzuki type multivalued (θ,R)-contraction and we will prove some fixed point results in the setting of a metric space equipped with a binary relation.

Generic singularities of minimax solutions to Hamilton--Jacobi equations [PDF]
, 2004 Minimax solutions are weak solutions to Cauchy problems involving Hamilton--Jacobi equations, constructed from generating families quadratic at infinity of their geometric solutions.

Networks and Spatial Economics, 2021 In this paper, we present two new inertial projection-type methods for solving multivalued variational inequality problems in finite-dimensional spaces. We establish the convergence of the sequence generated by these methods when the multivalued mapping ...
