Differential conformal superalgebras and their forms

[摘要] We introduce the formalism of differential conformal superalgebras, which we show leads to the ;;correct” automorphism group functor and accompanying descent theory in the conformal setting. As an application, we classify forms of N=2 and N=4 conformal superalgebras by means of Galois cohomology.
