Multiplicative spectral functions on some Banach function algebras
Nahid Bayati, Fereshteh Sady
In this paper, we study multiplicative functions on a natural Banach function algebra on a compact Hausdorff space , such that for all…
On 2-local diameter-preserving maps between C(X)-spaces
A. Jiménez-Vargas, Fereshteh Sady
The 2-locality problem of diameter-preserving maps between C(X)-spaces is addressed in this paper. For any compact Hausdorff space X with at least three points, we give an example…
Algebraic reflexivity of diameter-preserving linear bijections between -spaces
A. Jiménez-Vargas, Fereshteh Sady
We prove that if and are first countable compact Hausdorff spaces, then the set of all diameter-preserving linear bijections from to is algebraically reflexiv…
Isometries between completely regular vector-valued function spaces
Mojtaba Mojahedi, Fereshteh Sady
In this paper, first we study surjective isometries (not necessarily linear) between completely regular subspaces and of and where and are loc…
Composition in Modulus Maps on Semigroups of Continuous Functions
Bagher Jafarzadeh, Fereshteh Sady
For locally compact Hausdorff spaces and , and function algebras and on and , respectively, surjections satisfying norm multiplicative…
Additive jointly separating maps and ring homomorphisms
Fereshteh Sady, Masoumeh Najafi Tavani
Let and be compact Hausdorff spaces, and be real or complex normed spaces and be a subspace of . For a function , let $\coz(f)$ be the…
Lattice isomorphisms between certain sublattices of continuous functions
Vahid Ehsani, Fereshteh Sady
Let be the lattice of all continuous functions on a compact Hausdorff space with values in the unit interval . We show that for compact Hausdorff spaces a…
Isometries on certain non-complete vector-valued function spaces
Mojtaba Mojahedi, Fereshteh Sady
In the recent paper \cite{Hos}, surjective isometries, not necessarily linear, between vector-valued absolutely continuous function…
Jointly separating maps between vector-valued function spaces
Z. Pourghobadi, M. Najafi Tavani, F. Sady
Let and be compact Hausdorff spaces, and be real or complex Banach spaces, and be a subspace of . In this paper we study linear operators $S,T: A(X…
A note on nonlinear isometries between vector-valued function spaces
Arya Jamshidi, Fereshteh Sady
In this paper, we investigate the general form of surjective (not necessarily linear) isometries T : A-> B between subspaces A and B of C(X;E) and C(Y;F), respectively.
