Composition in Modulus Maps on Semigroups of Continuous Functions

Bagher Jafarzadeh, Fereshteh Sady

For locally compact Hausdorff spaces $X$ and $Y$ , and function algebras $A$ and $B$ on $X$ and $Y$ , respectively, surjections $T : A ⟶ B$ satisfying norm multiplicative…

Additive jointly separating maps and ring homomorphisms

Fereshteh Sady, Masoumeh Najafi Tavani

Let $X$ and $Y$ be compact Hausdorff spaces, $E$ and $F$ be real or complex normed spaces and $A (X, E)$ be a subspace of $C (X, E)$ . For a function $f \in C (X, E)$ , let $\coz(f)$ be the…

Lattice isomorphisms between certain sublattices of continuous functions

Vahid Ehsani, Fereshteh Sady

Let $C (X, I)$ be the lattice of all continuous functions on a compact Hausdorff space $X$ with values in the unit interval $I = [0, 1]$ . We show that for compact Hausdorff spaces $X$ a…
