Fredholm linear operators associated with ordinary differential equations on noncompact intervals
Electronic Journal of Differential Equations, 1999 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 ...

Some properties of demicompact operators related to quasi-Fredholm operators.
In this paper, we examine the relationship between demicompact operators and quasi-Fredholm operators. Additionally, we explore how demicompact linear operators relate to the upper B-Browder, Drazin, and B-Quasi-Fredholm spectra.

Solvability in the sense of sequences to some non-Fredholm operators
Electronic Journal of Differential Equations, 2013 We study the solvability of certain linear nonhomogeneous elliptic problems and show that under reasonable technical conditions the convergence in $L^2(mathbb{R}^d)$ of their right sides implies the existence and the convergence in $H^2(mathbb{R}^d ...
