✦ Synopsis

Following Leites, we define a cohomology for Lie superalgebras. A number of combinatorial identities are presented as well as two theorems which prove to be very useful in calculations. We then introduce the notion of deformations of Lie superalgebras and look at the deformations of the super-Poincar6 algebra and of osp(4/2).
