A Short Proof of Vladimirskii′s Theorem on Precompact Perturbations in Locally Convex Spaces
Published online by Cambridge University Press: 20 November 2018
Extract
Let T, P denote two continuous operators from E into F, where E and F are locally convex spaces. It is proved by L. Schwartz [8] and G. KÖthe [6] that if E and F are Fréchet spaces, T is a ϕ_-operator and P a compact operator, then T+P is a ϕ_-operator.
