Nonmaximal ideals and the Berkovich space of the algebra of bounded analytic functions
Jesús Araujo
We prove that the Berkovich space of the algebra of bounded analytic functions on the open unit disk of an algebraically closed nonarchimedean field contains multiplicative seminor…
Noncompactness and noncompleteness in isometries of Lipschitz spaces
Jesus Araujo, Luis Dubarbie
We solve the following three questions concerning surjective linear isometries between spaces of Lipschitz functions and , for strictly conve…
Biseparating maps between Lipschitz function spaces
Jesus Araujo, Luis Dubarbie
For complete metric spaces and , a description of linear biseparating maps between spaces of vector-valued Lipschitz functions defined on and is provided. In particu…
Stability and instability of weighted composition operators
Jesus Araujo, Juan J. Font
Let . A continuous linear operator $T:C(X) \ra C(Y)$ is said to be {\em -disjointness preserving} if $\vc (Tf)(Tg)\vd_{\infty} \le ε$, whenever satisfy $\vc f…
Multiplicative bijections of semigroups of interval-valued continuous functions
Jesus Araujo
We characterize all compact and Hausdorff spaces which satisfy that for every multiplicative bijection on , there exist a homeomorphism and a continuo…
Examples and counterexamples of type I isometric shifts
Jesus Araujo
We provide examples of nonseparable spaces for which C(X) admits an isometric shift of type I, which solves in the negative a problem proposed by Gutek {\em et al.} (J. Funct.…
