Polynomially spectrum-preserving maps between commutative Banach algebras

Osamu Hatori, Takeshi Miura, Hiroyuki Takagi

Let $A$ and $B$ be unital semi-simple commutative Banach algebras. In this paper we study two-variable polynomials $p$ which satisfy the following property: a map $T$ from $A$ onto…

Multiplicatively spectrum-preserving and norm-preserving maps between invertible groups of commutative Banach algebras

Osamu Hatori, Takeshi Miura, Hiroyuki Takaggi

Let $A$ and $B$ be unital semisimple commutative Banach algebras and $T$ a map from the invertible group $A^{- 1}$ onto $B^{- 1}$ . Linearity and multiplicativity of the map are not a…
