Automorphisms and twisted forms of the N = 1, 2, 3 Lie conformal

Zhihua Chang, Arturo Pianzola
We classify the N = 1, 2, 3 superconformal Lie algebras of Schwimmer and
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.
