We give an example of a locally A-convex algebra which is neither m-convex nor uniformly ^-convex. This example is used to answer some questions on ^-convex algebras (see symbol 4). We especially show that Michael's problem (in m-convex algebras) is equivalent to the same problem in A-convex algebras. Finally some questions on bounded sets in A-convex algebras are studied.
