On Singer-Wermer conjecture in Frechet algebras
S. R. Patel
We construct two Frechet algebras admitting countably many mutually inequivalent Frechet algebra topologies. The second example is a modification of the maiden (and first) example…

On discontinuity of derivations, inducing non-unique complete metric topologies
S. R. Patel
We give a simple method for constructing commutative Frechet algebras which admit two inequivalent Frechet algebra topologies. The result is applied to show that the action of any…
