Spectral and Essential Spectral Analysis of Finite-Rank Perturbations of Unbounded Diagonal Operators on Non-Archimedean Hilbert Spaces

Teylama Miabey

We study the spectral properties of a class of unbounded linear operators on a non-Archimedean Hilbert space $E_{ω}$ . More precisely, we consider operators of the form \[ T=D+F,\qqua…

Algebraic Geometry over Non-Algebraically Closed Fields -- A-Coherent Sheaves over a Ringed Space

Hamet Seydi, Teylama Miabey

In this paper, we investigate the properties of $A$ -coherent and $A$ -quasi-coherent sheaves within the framework of algebraic geometry over non-algebraically closed fields. We defi…

Spectral analysis for a class of bounded linear operators

Teylama Miabey

We study the Spectral Analysis for a class of bounded linear operators T = D + F in a non Archimedean Hilbert space E, where D is a diagonal linear operator and where F is a finite…
