Left (right) pseudospectrum and left (right) condition pseudospectrum of bounded linear operators on ultrametric Banach spaces
Jawad Ettayb
In this note, we introduce and study the left (right) pseudospectrum and left (right) condition pseudospectrum of bounded linear operators on ultrametric Banach spaces. We prove so…
Condition pseudospectrum of operator pencils on non-archimedean Banach spaces
Jawad Ettayb
This paper deals with the condition pseudospectrum and essential condition pseudospectrum of operator pencils on n.a Banach spaces. We give a characterization of the condition pseu…
A Hille-Yoshida-Phillips theorem for discrete semigroups on complete ultrametric locally convex spaces
Jawad Ettayb
Let be a complete Hausdorff locally convex space over let such that is analytic on its domain. In this paper, we give a nec…
Further results on -adic semigroup of contractions
Jawad Ettayb
Let be an ultrametric Banach space over In this note, we obtain a new necessary and sufficient conditions on the resolvent of such that for each $m\in\mat…
Structured pseudospectrum and structured condition pseudospectrum of non-archimedean matrices
Jawad Ettayb
In this paper, the structured pseudospectrum of non-archimedean matrices and structured pseudospectrum of non-archimedean matrix pencils are introduced. Many results are proved abo…
