Counterterms in extended supergravities
Abstract
Geometrical invariants respecting all necessary symmetries of the theory are shown to exist, starting from the 8th (4th) loop approximation in N = 8 ( N = 4) on-shell supergravity. 3-loop counterterms are presented on a linearized level for N = 4 and N = 8 theories. The corresponding 3-loop non-linear invariants are discussed.
