This note introduces a
class of topological algebras, called A-convex, which generalize the notion of
locally m-convex algebras. They include a number of function space algebras
which are not locally m-convex. Certain of these algebras admit a modified
Gel’fand type representation in a space of vector-valued functions without
invoking commutativity requirements. One seemingly obtains a new way of
representing locally m-convex algebras. A-convex algebras are locally m-convex
under the assumption of completeness of certain factor algebras in a suitable
topology.
