Condition pseudospectra of multivalued linear operator pencils on non-Archimedean Banach spaces

In this article, we introduce and study the concept of pseudospectra and condition pseudospectra of bounded closed linear relation pencils on non-Archimedean Banach spaces. We establish a characterization of the condition pseudospectra of bounded closed linear relation pencils and we give a relationship between the condition pseudospectra and the pseudospectra of bounded closed linear relation pencils on non-Archimedean Banach spaces.
