Finite-codimensional subspaces of locally convex spaces
A Hille-Yosida Theorem is proved on convenient vector spaces, a class, which contains all sequentially complete locally convex spaces. The approach is governed by convenient analysis and the credo that many reasonable questions concerning strongly continuous semigroups can be proved on the subspace of smooth vectors. Examples from literature are reconsidered by these simpler methods and some applications to the theory of infinite dimensional heat equations are given.
This article is devoted to a study of locally convex topologies on (where is an open subset of the locally convex topological vector space and is the set of all complex valued holomorphic functions on ). We discuss the following topologies on :(a) the compact open topology ,(b) the bornological topology associated with ,(c) the ported topology of Nachbin ,(d) the bornological topology associated with ; and(e) the topological of Nachbin.For balanced we show these topologies are...
Let and be two complex Banach spaces, a nonempty subset of and a compact subset of . The concept of holomorphy type between and , and the natural locally convex topology on the vector space of all holomorphic mappings of a given holomorphy type from to were considered first by L. Nachbin. Motived by his work, we introduce the locally convex space of all germs of holomorphic mappings into around of a given holomorphy type , and study its interplay with and some...
