Attractors for an Energy‐Damped Viscoelastic Plate Equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a class of non‐autonomous beam/plate equations with an integro‐differential damping given by a possibly degenerate memory and an energy damping given by a nonlocal ε$$ \varepsilon $$‐perturbed coefficient. For each ε>0$$ \varepsilon >0 $$, we show that the dynamical system generated by the weak solutions of the ...

Some extremal properties of section spaces of Banach bundles and their duals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
When X is a compact Hausdorff space and E is a real Banach space there is a considerable literature on extremal properties of the space C(X,E) of continuous E-valued functions on X. What happens if the Banach spaces in which the functions on X take their

Vector-valued holomorphic and harmonic functions

open access: yesConcrete Operators, 2016
Holomorphic and harmonic functions with values in a Banach space are investigated. Following an approach given in a joint article with Nikolski [4] it is shown that for bounded functions with values in a Banach space it suffices that the composition with

The Automorphism Group of a Banach Principal Bundle with {1}-structure

open access: yes, 2011
A {1}-structure on a Banach manifold M (with model space E) is an E-valued 1-form on M that induces on each tangent space an isomorphism onto E. Given a Banach principal bundle P with connected base space and a {1}-structure on P, we show that its ...

Fixed points and iteration of a nonexpansive mapping in a Banach space

open access: yes, 1976
The following result is shown. If T is a nonexpansive mapping from a closed convex subset D of a Banach space into a compact subset of D and xl is any point in D, then the sequence {xj} defined by x,,+I = 2-1 (xn + Tx,,) converges to a fixed point of T ...

Existence of Weak Solutions for a Degenerate Goursat‐Type Linear Problem

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT For a generalization of the Gellerstedt operator with mixed‐type Dirichlet boundary conditions to a suitable Tricomi domain, we prove the existence and uniqueness of weak solutions of the linear problem and for a generalization of this problem.

Nonwandering operators in Banach space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
We introduce nonwandering operators in infinite-dimensional separable Banach space. They are new linear chaotic operators and are relative to hypercylic operators, but different from them.

Optimal domain of $q$-concave operators and vector measure representation of $q$-concave Banach lattices [PDF]

open access: yes, 2015
Given a Banach space valued $q$-concave linear operator $T$ defined on a $\sigma$-order continuous quasi-Banach function space, we provide a description of the optimal domain of $T$ preserving $q$-concavity, that is, the largest $\sigma$-order continuous

Linear $L$-positive sets and their polar subspaces

open access: yes, 2012
In this paper, we define a Banach SNL space to be a Banach space with a certain kind of linear map from it into its dual, and we develop the theory of linear $L$-positive subsets of Banach SNL spaces with Banach SNL dual spaces.

A forward–backward splitting algorithm for the minimization of non-smooth convex functionals in Banach space [PDF]

open access: yes, 2008
We consider the task of computing an approximate minimizer of the sum of a smooth and a non-smooth convex functional, respectively, in Banach space. Motivated by the classical forward–backward splitting method for the subgradients in Hilbert space, we ...
