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.

Fredholm theory in ordered Banach algebras
This paper illustrates some initial steps taken in the effort of unifying the theory of positivity in ordered Banach algebas (OBAs) with the general Fred-holm theory in Banach algebras.

Existence and stability of solution for time-delayed nonlinear fractional differential equations
The objective of this study is to analyze the existence and stability of solutions for a mathematical model of nonlinear systems of time-delayed fractional differential equations involving Atangana-Baleanu-Caputo ([Formula: see text]) fractional ...

. The purpose of this paper is to prove that the spectrum of the non-self-adjoint oneparticle Hamiltonian proposed by J. Feinberg and A. Zee (Phys. Rev. E 59 (1999), 6433-6443) has interior points.

The basic propositions on defect numbers, root numbers and indices of linear operators [PDF]
: In this work, we use the notion of the measure of noncompactness in order to establish some results concerning the class of semi-Fredholm and Fredholm operators.

Discrete random electromagnetic Laplacians
We consider discrete random magnetic Laplacians in the plane and discrete random electromagnetic Laplacians in higher dimensions. The existence of these objects relies on a theorem of Feldman-Moore which was generalized by Lind to the nonabelian case ...
