Common fixed point of g-approximative multivalued mapping in ordered partial metric space

Fixed Point Theory and Applications, 2013
In this paper, we introduce g-approximative multivalued mappings to a partial metric space. Based on this definition, we give some new definitions.

Multistep-type construction of fixed point for multivalued ρ-quasi-contractive-like maps in modular function spaces [PDF]

Arab Journal of Mathematical Sciences, 2021
Purpose – In this paper, the explicit multistep, explicit multistep-SP and implicit multistep iterative sequences are introduced in the context of modular function spaces and proven to converge to the fixed point of a multivalued map T such that PρT, an ...

Continuous selections of multivalued mappings

, 2014
This survey covers in our opinion the most important results in the theory of continuous selections of multivalued mappings (approximately) from 2002 through 2012.

Recent advances in the Lefschetz fixed point theory for multivalued mappings

Results in Nonlinear Analysis, 2021
In 1923 S. Lefschetz proved the famous fixed point theorem known as the Lefschetz fixed point theorem (comp. [5], [9], [20], [21]. The multivalued case was considered for the first time in 1946 by S. Eilenberg and D. Montgomery ([10]).

Approximation of Fixed Points of Multivalued Generalized (α,β)-Nonexpansive Mappings in an Ordered CAT(0) Space

Mathematics, 2021
The purpose of this article is to initiate the notion of monotone multivalued generalized (α,β)-nonexpansive mappings and explore the iterative approximation of the fixed points for the mapping in an ordered CAT(0) space.

Complexity Of Multivalued Maps

, 2011
We consider the topological entropy of maps that in general, cannot be described by one-dimensional dynamics. In particular, we show that for a multivalued map F generated by singlevalued maps, the topological entropy of any of the single-value map bounds the topological entropy of F from below.

Weak index pairs and the Conley index for discrete multivalued dynamical systems. Part II: properties of the index

, 2017
Motivation to revisit the Conley index theory for discrete multivalued dynamical systems stems from the needs of broader real applications, in particular in sampled dynamics or in combinatorial dynamics. The new construction of the index in [B. Batko and

An ordered framework for partial multivalued functors

The category Rel of sets and relations intimately ties the notions of function, partial multivalued function, and direct image under a function through the description of Rel as the Kleisli category of the covariant power set functor on Set. We present a

ON MULTIVALUED f-NONEXPANSIVE MAPS

Demonstratio Mathematica, 1999
The authors prove coincidence, fixed point, and convergence theorems which extend previous results by G. L. Acedo and H.-K. Xu, W. G. Dotson, G. Jungck and S. Sessa, and E. Lami Dozo.
