Abstract

In this paper, we study bijective linear maps θ:A→B between AW^⁎-algebras preserving either zero products or range orthogonality. Such a map is automatically continuous, and provides an algebra or a ⁎-algebra isomorphism π(⋅)=θ(⋅)θ^⁎⁎(1)⁻¹ from A onto B. Our results extend previous works for the case of W^⁎-algebras, and also cover such maps between C^⁎-algebras satisfying an extra assumption on preserving abelian C^⁎-subalgebras.
