Metric domains, holomorphic mappings and nonlinear semigroups [PDF]

open access: yesAbstract and Applied Analysis, 1998
We study nonlinear semigroups of holomorphic mappings on certain domains in complex Banach spaces. We examine, in particular, their differentiability and their representations by exponential and other product formulas.

On Uniformly Generalized Lipschitzian Mappings [PDF]

open access: yesFixed Point Theory and Applications, 2010
We consider another class of generalized Lipschitzian type mappings and utilize the same to prove fixed point theorems for asymptotically regular and uniformly generalized Lipschitzian one-parameter semigroups of self-mappings defined on bounded metric ...

Semigroups of mappings on graphs

open access: yesSemigroup Forum, 1983
At present, there are quite a few investigations in the theory of semigroups devoted to semigroups of mappings on graphs. Up to now, endomorphism semigroups of graphs, extensive transformation semigroups of graphs, coloring semigroups of graphs and other semigroups of special mappings on graphs have been studied.

Commuting semigroups of holomorphic mappings [PDF]

open access: yesMATHEMATICA SCANDINAVICA, 2008
Let $S_{1}=\left\{F_t\right\}_{t\geq 0}$ and $S_{2}=\left\{G_t\right\}_{t\geq 0}$ be two continuous semigroups of holomorphic self-mappings of the unit disk $\Delta=\{z:|z|<1\}$ generated by $f$ and $g$, respectively. We present conditions on the behavior of $f$ (or $g$) in a neighborhood of a fixed point of $S_{1}$ (or $S_{2}$), under which the ...

Attractors of Compactly Generated Semigroups of Regular Polynomial Mappings [PDF]

open access: yesComplexity, 2018
We investigate the metric space of pluriregular sets as well as the contractions on that space induced by infinite compact families of proper polynomial mappings of several complex variables.

Fixed point properties for semigroups of nonexpansive mappings on convex sets in dual Banach spaces [PDF]

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018
It has been a long-standing problem posed by the first author in a conference in Marseille in 1990 to characterize semitopological semigroups which have common fixed point property when acting on a nonempty weak* compact convex subset of a dual Banach ...

Common Solutions of Generalized Mixed Equilibrium Problems, Variational Inclusions, and Common Fixed Points for Nonexpansive Semigroups and Strictly Pseudocontractive Mappings [PDF]

open access: yesJournal of Applied Mathematics, 2011
We introduce a new iterative scheme by shrinking projection method for finding a common element of the set of solutions of generalized mixed equilibrium problems, the set of common solutions of variational inclusion problems with set-valued maximal ...

Fixed point property for nonexpansive mappings and nonexpansive semigroups on the unit disk [PDF]

open access: yesRevista Integración, 2015
For closed convex subsets D of a Banach spaces, in 2009, Tomonari Suzuki [11] proved that the fixed point property (FPP) for nonexpansive mappings and the FPP for nonexpansive semigroups are equivalent.

Characterizing some regularities of ordered semigroups by their anti-hybrid ideals [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
We focus on mappings called hybrid structures. A hybrid structure can be regarded as a combination of a soft set and a fuzzy set. Therefore, with the help of the products of union softs sets and fuzzy sets, we can define a new product of hybrid ...

Strong convergence theorem for amenable semigroups of nonexpansive mappings and variational inequalities [PDF]

open access: yesFixed Point Theory and Applications, 2011
In this paper, using strongly monotone and lipschitzian operator, we introduce a general iterative process for finding a common fixed point of a semigroup of nonexpansive mappings, with respect to strongly left regular sequence of means defined on an ...
