Representations and cohomologies of differential 3-Lie algebras with any weight
Abstract
The purpose of the present paper is to study representations and cohomologies of differential 3-Lie algebras with any weight. We introduce the representation of a differential 3-Lie algebra. Moreover,we develop cohomology theory of a differential 3-Lie algebra. We also depict the relationship between the cohomologies of a differential 3-Lie algebra and its associated differential Leibniz algebra with weight zero. The deformation and O-operator of differential 3-Lie algebras are also investigated. Finally, we consider abelian extensions of differential 3-Lie algebras.
