Fréchet algebras, formal power series, and automatic continuity
S. R. Patel · Studia Mathematica · 2008
We describe all those commutative Fréchet algebras which may be continuously embedded in the algebra $\mathbb{C}[[X]]$ in such a way that they contain the polynomials. It is shown that these algebras (except $\mathbb{C}[[X]]$ itself) always satisfy
