Characterizations of Lie n-derivations of unital algebras with nontrivial idempotents
Yana Ding, Jiankui li
Let A be a unital algebra with a nontrivial idempotent e, and f=1-e. Suppose that A satisfies that exe.eAf={0}=fAe.exe implies exe=0 and eAf.fxf={0}=fxf.fAe implies fxf=0 for each…

Left derivable or Jordan left derivable mappings on Banach algebras
Yana Ding, Jiankui Li
Let d be a linear mapping from a unital Banach algebra A into a unital left A-module M, and w in Z(A) be a left separating point of M. We show that the following three conditions a…
