Abstract
Purpose
The paper deals with ultrametric bounded Fredholm operators and approximate pseudospectra of closed and densely defined (resp. bounded) linear operators on ultrametric Banach spaces.
Design/methodology/approach
The author used the notions of ultrametric bounded Fredholm operators and approximate pseudospectra of operators.
Findings
The author established some results on ultrametric bounded Fredholm operators and approximate pseudospectra of closed and densely defined (resp. bounded) linear operators on ultrametric Banach spaces.
Originality/value
The results of the present manuscript are original.
