Perturbation theory of p-adic Fredholm and semi-Fredholm operators
Let \(X,Y\) be a non-archimedean (n.a.) Banach spaces over a n.a. valued field \(\mathbb K\,\) [see \textit{A. C. M. van Rooij,} Non-Archimedean functional analysis (1978; Zbl 0396.46061)]. A continuous linear operator \(T:X\to Y\) is called semi-Fredholm\((-)\) provided that \(\eta(T):= \dim \ker(T) < \infty\) and the range \(R(T)\) is closed in \(Y,\)

Static spectra and static families of Fredholm-type operators under tensor product
In this study, we introduce the static spectrum, the Weyl static families, the upper semi-Fredholm static families, and the Browder static families. These families consist of bounded linear operators parameterized by a scalar variable.

No-flux boundary problems involving p(x)-Laplacian-like operators
In this article we obtain weak solutions for a class nonlinear elliptic problems for the $p(x)$-Laplacian-like operators under no-flux boundary conditions.

Fredholm linear operators associated with ordinary differential equations on noncompact intervals
In the noncompact interval $J=[a,infty )$ we consider a linear problem of the form $Lx=y,; x in S$, where $L$ is a first order differential operator, $y$ a locally summable function in $J$, and $S$ a subspace of the Fr'{e}chet space of the locally ...

A characterization of Wolf and Schechter essential pseudospectra
The aim of this paper is to provide new results on the Wolf and Schechter essential pseudospectra of bounded linear operators on a Banach space. More precisely, we characterize the Wolf and Schechter essential pseudospectra by using the notion of ...
