Isometries and hermitian operators on spaces of vector-valued Lipschitz maps

Shiho Oi

We study hermitian operators and isometries on spaces of vector-valued Lipschitz maps with the sum norm: $∥ \cdot ∥_{\infty} + L (\cdot)$ . There are two main theorems in this paper. F…

Tingley's problem on uniform algebras

Osamu Hatori, Shiho Oi, Rumi Shindo Togashi

We prove that a surjective isometry between the unit spheres of two uniform algebras is extended to a surjective real-linear isometry between the uniform algebras. It provides the…
