Different models of field theories in two dimensions can be described by the action Tr .F. In the presence of a curved background, we construct local supersymmetry-like transformations under which the action is invariant. Furthermore, by analyzing the cohomology of the theory we show the absence of
## Abstract In this contribution we describe computational tools that permit the evaluation of multiβloop scattering amplitudes in π© = 8 supergravity, in terms of amplitudes in π© = 4 superβYangβMills theory. We also discuss the remarkable ultraviolet behavior of π© = 8 supergravity, which follows fr
## Abstract Concrete calculations have pointed out that amplitudes in perturbative gravity exhibit unanticipated cancellations taming their ultraviolet behaviour independently of supersymmetry. Similar ultraviolet behaviour of π© = 4 superβYangβMills and π© = 8 maximal supergravity has explicitly bee
