*讲座内容简介：
In this talk, we introduce the representations and cohomologies of differential 3-Lie algebras with any weight. Deformations and abelian extensions of differential 3-Lie algebras are interpreted by using lower degree cohomology groups. We also characterize the relationship between the cohomologies of a differential 3-Lie algebra and its associated differential Leibniz algebra with weight zero.
