Fixed points of asymptotically regular semigroups in Banach spacesSpringer Science and Business Media LLC - Tập 46 - Trang 89-118 - 1997
Jarosław Górnicki
In this paper we study in Banach spaces the existence of fixed points of
(nonlinear) asymptotically regular semigroups. We establish for these semigroups
some fixed point theorems in spaces with weak uniform normal structure, in a
Hilbert space, inL p spaces, in Hardy spacesH p and in Sobolev spacesW r.p for 1... hiện toàn bộ
An inertial-viscosity algorithm for solving split generalized equilibrium problem and a system of demimetric mappings in Hilbert spacesSpringer Science and Business Media LLC - Tập 72 - Trang 1599-1628 - 2022

In this paper, we introduce a new inertial-viscosity approximation method for
solving a split generalized equilibrium problem and common fixed point problem
in real Hilbert spaces. The algorithm is designed such that its convergence does
not require the norm of the bounded linear operator underlying the split
equilibrium problem. Moreover, a strong convergence result is proved under mild
condition... hiện toàn bộ
Groups of module automorphisms of finite rankSpringer Science and Business Media LLC - - 2016
B. A. F. Wehrfritz
Let R be any ring, M an R-module and G a subgroup of $$\hbox
{Aut}_{\mathrm{R}}\hbox {M}$$ of finite rank. We compare the R-module structure
of certain R-G images of M with that of certain R-G submodules of M. (We are
treating M here as an R-G bimodule). For example, if A $$=$$ [M, G] and
$$\hbox {B}=\hbox {M/C}_{\mathrm{M}}\hbox {(G)}$$ , then we prove that as
R-modules, A is Artinian if B is A... hiện toàn bộ
Approximation of complex q-Baskakov-Schurer-Szasz-Stancu operators in compact disksSpringer Science and Business Media LLC - Tập 72 - Trang 1919-1935 - 2022
Larisa Cheregi
This paper deals with approximation properties of complex
q-Baskakov-Schurer-Szasz-Stancu operators on compact disks and the results show
the overconvergence phenomenon for these complex operators. Voronovskaja-type
results with quantitative estimates and the exact order of simultaneous
approximation in compact disks are obtained.
