三角代数上σ-可导映射的可加性
Additivity ofσ-Derivable Maps on Triangular Algebras
摘要
Abstract
Let U be a triangular algebra,δ be a mapping from U into itself (without assumption of additivity),andσ be an automorphism of U.By using the method of algebraic decomposition,we proved that ifδsatisfiedδ(xy )=δ(x)y +σ(x)δ(y )for all x ,y ∈U,thenδwas an additiveσ-derivation.关键词
