Biderivations serve as bilinear mappings that satisfy derivation conditions in each argument of a Lie algebra. They offer a refined tool to probe the structure of Lie algebras, delineating both inner ...

We study the classification problem for left-symmetric algebras with commutation Lie algebra $\germ{gl}$(n) in characteristic 0. The problem is equivalent to the classification of étale affine ...

Annals of Mathematics, a distinguished journal of research papers in pure mathematics, was founded in 1884. Annals of Mathematics is published bimonthly with the cooperation of Princeton University ...
