Every commutative JB$$^*$$-triple satisfies the complex Mazur–Ulam property [PDF]

open access: hybridAnnals of Functional Analysis, 2022
AbstractWe prove that every commutative JB$$^*$$∗-triple, represented as a space of continuous functions$$C_0^{\mathbb {T}}(L),$$C0T(L),satisfies the complex Mazur–Ulam property, that is, every surjective isometry from the unit sphere of$$C_0^{\mathbb {T}}(L)$$C0T(L)onto the unit sphere of any complex Banach space admits an extension to a surjective ...

Every non-smooth 2-dimensional Banach space has the Mazur–Ulam property [PDF]

open access: greenLinear Algebra and its Applications, 2021
A Banach space $X$ has the $Mazur$-$Ulam$ $property$ if any isometry from the unit sphere of $X$ onto the unit sphere of any other Banach space $Y$ extends to a linear isometry of the Banach spaces $X,Y$. A Banach space $X$ is called $smooth$ if the unit ball has a unique supporting functional at each point of the unit sphere.

The Mazur–Ulam property for abelian $C^*$-algebras [PDF]

open access: bronzeStudia Mathematica, 2022
The famous Mazur-Ulam theorem states that every surjective isometric mapping of a real normed space \(E\) to a real normed space \(F\) is affine. In a normed linear space, many properties of the space are determined by the action on the unit sphere of the space. Motivated by this, \textit{D.~Tingley} [Geom. Dedicata 22, 371--378 (1987; Zbl 0615.51005)]

The Mazur–Ulam property for uniform algebras [PDF]

open access: closedStudia Mathematica, 2022
We give a sufficient condition for a Banach space with which the homogeneous extension of a surjective isometry from the unit sphere of it onto another one is real-linear. The condition is satisfied by a uniform algebra and a certain extremely $C$-regular space of real-valued continuous functions.

The Mazur–Ulam property for the space of complex null sequences [PDF]

open access: greenLinear and Multilinear Algebra, 2018
Given an infinite set Γ , we prove that the space of complex null sequences, c0(Γ) , satisfies the Mazur–Ulam property, that is, for each Banach space X, every surjective isometry from the unit sph...

On the Mazur--Ulam property for the space of Hilbert-space-valued\n continuous functions [PDF]

open access: greenJournal of Mathematical Analysis and Applications, 2019
Let $K$ be a compact Hausdorff space and let $H$ be a real or complex Hilbert space with dim$(H_\mathbb{R})\geq 2$. We prove that the space $C(K,H)$ of all $H$-valued continuous functions on $K$, equipped with the supremum norm, satisfies the Mazur--Ulam property, that is, if $Y$ is any real Banach space, every surjective isometry $ $ from the unit ...

The Mazur-Ulam property for a Banach space which satisfies a separation condition [PDF]

open access: green, 2022
We study $C$-rich spaces, lush spaces, and $C$-extremely regular spaces concerning with the Mazur-Ulam property. We show that a uniform algebra and the real part of a uniform algebra with the supremum norm are $C$-rich spaces, hence lush spaces. We prove that a uniformly closed subalgebra of the algebra of complex-valued continuous functions on a ...
