From Anti-de Sitter Background to Superconformal World Sheet Symmetry
Toine Van Proeyen
**
Solutions of supergravity theories, with Killing vectors and spinors
satisfying a super-$adS$ algebra, determine world-volume actions with
superconformal symmetry. This connection is made explicit, and makes
use of kappa-symmetry and its gauge fixing. For the case of $adS_2$,
following the same steps, one obtains `relativistic superconformal mechanics'.
The last reference below is nearly overlapping with the talk I gave here.
