✦ Synopsis


All solutions to the consistency equations are determined which have to be satisfied by anomalies in gravitational theories with a de Sitter-invariant groundstate. They turn out to be identical with the solutions for a Poincar6-invariant groundstate.

In three-dimensional de Sitter space S 3 1 and anti-de Sitter space H 3 1 , we generalize the classical BΓ€cklund theorem. Moreover, we obtain explicit forms of BΓ€cklund transformations (BTs) in the Tchebyshev coordinates and investigate the relation of loop group actions and BTs in S 3 1 .
