We classify the N = 1, 2, 3 superconformal Lie algebras of Schwimmer andView original: http://arxiv.org/abs/1201.5410
Seiberg by means of di?erential non-abelian cohomology, and describe the
general philosophy behind this new technique. The structure of the group
(functor) of automorphisms of the corresponding Lie conformal superalgebra is a
key ingredient of the proof.
