Diameter preserving maps on function spaces
Springer (2016-08-16)In this paper we describe, under certain assumptions, surjective diameter preserving mappings when defined between function spaces, not necessarily algebras, thus extending most of the previous results for these operators. ... -
Korovkin-Type Results on Convergence of Sequences of Positive Linear Maps on Function Spaces
Springer Verlag (2019-11-11)In this paper, we deal with the convergence of sequences of positive linear maps to a (not assumed to be linear) isometry on spaces of continuous functions. We obtain generalizations of known Korovkin-type results and ...

Multilinear isometries on function algebras
Taylor & Francis (2015)Let be function algebras (or more generally, dense subspaces of uniformly closed function algebras) on locally compact Hausdorff spaces , respectively, and let Z be a locally compact Hausdorff space. A -linear map is called ...

Nonlinear diameter preserving maps on function spaces
Taylor & Francis (2020-01-01)In this paper we study nonlinear diameter preserving mappings defined between function spaces and obtain generalizations of, basically, all known results concerning diameter preservers. In particular, we give a complete ...

Norm-additive in modulus maps between function algebras
Duke University Press (2014)The main purpose of this paper is to characterize norm-additive in modulus, not necessarily linear, maps defined between function algebras (not necessarily unital or uniformly closed). In fact, for function algebras A and ...

Real-Linear Isometries and Jointly Norm-Additive Maps on Function Algebras
Springer (2015)In this paper, we describe into real-linear isometries defined between (not necessarily unital) function algebras and show, based on an example, that this type of isometries behaves differently from surjective real-linear ...

Real-Multilinear Isometries on Function Algebras
Springer International Publishing (2017)Let A 1 ,...,A k be function algebras (or more generally, dense subspaces of uniformly closed function algebras) on locally compact Haus- dorff spaces X 1 ,...,X k , respectively, and let Y be a locally ...
