Abstract
For metric spaces and , normed spaces and , and certain subspaces and of vector-valued continuous functions, we obtain a complete characterization of linear and bijective maps preserving common zeros, that is, maps satisfying the property \setcounter{equation}{15} \label{dub} Z(f)\cap Z(g)\neq \emptyset \Longleftrightarrow Z(Tf)\cap Z(Tg)\neq \emptyset for any , where . Moreover, we provide some examples of subspaces for which the automatic continuity of linear bijections having the property (\ref{dub}) is derived.
