On pencil of bounded linear operators on non-archimedean Banach spaces

In this paper, we introduce and check some properties of pseudospectrum and some approximation of a pencil of bounded linear operators on non-archimedean Banach Spaces. Our main result extends some results for a pencil of bounded linear operators on non-archimedean Banach spaces and we give some exa...

Zusammenfassung:In this paper, we introduce and check some properties of pseudospectrum and some approximation of a pencil of bounded linear operators on non-archimedean Banach Spaces. Our main result extends some results for a pencil of bounded linear operators on non-archimedean Banach spaces and we give some examples to support our work.
