In this note we prove the existence of operators which are not Tauberian even though they satisfy properties about restrictions being Tauberian. The operators are defined on Banach spaces which contain a somewhat reflexive, non-reflexive subspace. Th

Some characterizations of the conjugate of a Banach–Stone map T : C(X) C(Y) between the non–Archimedean spaces of continuous functions C(X) and C(Y) are studied. The main result that T′ : C(Y)′ C(X)′ is a Banach–Stone map if and only if T

The authors develop the Fredholm theory for semi-compact operators on non-archimedean locally convex spaces. This theory coincides with Schikhof's Fredholm theory for compact operators on Banach spaces which fails for non-complete normed spaces.

In this paper we give several descriptions of padic semi-Fredholm operators in terms of the preservation of orthogonal sequences and compactoid sets.

In a recent paper, M.Z.M.C. Soares [3] introduced the concepts of Chebyshev radii and centers in a non-archimedean normed space E and posed some of the main problems in the non-archimedean theory of best simultaneous approximation. In this paper we p

The Fredholm theory for compact operators on a non-archimedean Banach space E, as recently developed by W. Schikhof, does not work if the hypothesis of the completeness of E is dropped. This observation led the authors to introduce two new ideals of
