In this talk, the structure of the linear maps between two different matrix spaces preserving disjointness is characterized. Moreover, some related results for zero product preservers between matrix algebras are obtained. This is a join work with Chi-Kwong Li, Ya-Shu Wang, Ngai-Ching Wong.Keyword: disjointness preserver, zero product, matrix spaces, matrix algebras
