چکیده
Let X and Y be real normed spaces f : ? a surjective mapping. Then satisfies { ? ( x ) + y , ? } = ? if only is phase equivalent to linear isometry, that is, ? U where isometry 1 . This Wigner's type result for spaces.

Approximate Isometries on Finite-dimensional Normed Spaces
Every ε-isometry u between real normed spaces of the same finite dimension which maps the origin to the origin may by uniformly approximated to within 2ε by a linear isometry. Under a smoothness hypothesis, necessary and sufficient conditions are obtained for the same conclusion to hold for a given ε-isometry between infinite-dimensional Banach spaces.
متن کاملIsometries between spaces of homogeneous polynomials
We derive Banach-Stone theorems for spaces of homogeneous polynomials. We show that every isometric isomorphism between the spaces of n-homogeneous approximable polynomials on real Banach spaces E and F is induced by an isometric isomorphism of E′ onto F ′. With an additional geometric condition we obtain the analogous result in the complex case. Isometries between spaces of n-homogeneous integ...
متن کاملIsometries on Quasi–normed Cones and Bicompletion
We show that every quasi–norm p on a (real) cancellative cone X induces in a natural way an extended quasi–metric ep on X for which (X, ep) is an extended quasi–metric cone. We prove that the structure of a quasi– normed cone is preserved by bicompletion, under bijective isometries. In fact, we observe that isometries are not necessarily injective in this setting. Some illustrative examples are...

Aleksandrov problem. Examine whether the existence of a single conservative distance for some mapping T implies that T is an isometry. The Aleksandrov problem has been investigated in several papers (see [2, 3, 6–9, 13– 15, 20, 23, 26, 28]). Rassias and Šemrl [25] proved the following theorem for mappings satisfying the strong distance one preserving property (SDOPP), that is, for every x, y ∈ ...
