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…

Equivalence Classes of Boundary Conditions in Gauge Theory on $Z_{3}$ Orbifold

Yoshiharu Kawamura, Teppei Kinami, Takeshi Miura

We study equivalence classes of boundary conditions in gauge theory on the orbifold $T^{2} / Z_{3}$ . Orbifold conditions and those gauge transformation properties are given and the gauge…
