TY - JOUR AU - Liang, Xinfeng AU - Zhang, Mengya PY - 2024 TI - Triangular algebras with nonlinear higher Lie n-derivation by local actions JO - AIMS Mathematics SP - 2549 EP - 2583 VL - 9 IS - 2 AB - This paper was devoted to the study of the so-called nonlinear higher Lie n-derivation of triangular algebras T , where n is a nonnegative integer greater than two. Under some mild conditions, we proved that every nonlinear higher Lie n-derivation by local actions on the triangular algebras is of a standard form. As an application, we gave a characterization of higher Lie n-derivation by local actions on upper triangular matrix algebras, block upper triangular matrix algebras and nest algebras, respectively.
