Abstract

We classify the $N=1,2,3$ superconformal Lie algebras ofSchwimmer and Seiberg by means of differential non-abeliancohomology, and describe the general philosophy behind thisnew technique. The structure of the group (functor) ofautomorphisms of the corresponding Lie conformalsuperalgebra is a key ingredient of the proof.
