Embeddings of Fréchet spaces in uniform Fréchet algebras
Entire functions and equicontinuity of power maps in Baire algebras.
We obtain that the power maps are equicontinuous at zero in any Baire locally convex algebra with a continuous product in which all entire functions operate; whence is m-convex in the commutative case. As a consequence, we get the same result of Mityagin, Rolewicz and Zelazko for commutative B0-algebras.
