广义矩阵代数上的一类非线性局部可导映射
A Class of Nonlinear Local Derivable Maps on Generalized Matrix Algebras
摘要
Abstract
Let(y)=(y)((A),(M),(N),(B))be a generalized matrix algebra,and φ:(y)→(y) be a map(without the assumption of additivity).Using the method of algebraic decomposition,we proved that if φ(XY)=φ(X)Y+Xφ(Y) held for any X,Y∈(y) and at least one of X and Y was idempotent,then φ was an additive derivation on (y).关键词
