Chapter 1 Wolfgang Kummer and the Vienna School of Dilaton ( Super - ) Gravity

چکیده
Wolfgang Kummer was well known for his passion for axial gauges and for the formulation of gravity in terms of Cartan variables. The combination of the two applied to two-dimensional dilaton gravity is the basis of the “Vienna School”, which provided numerous significant results over the last seventeen years. In this review we trace the history of this success with particular emphasis on dilaton supergravity. We also present some previously unpublished results on the structure of non-local vertices in quantum dilaton supergravity with non-minimally coupled matter.

متن کاملCanonical analysis of cosmological topologically massive gravity at the chiral point
Wolfgang Kummer was a pioneer of two-dimensional gravity and a strong advocate of the first order formulation in terms of Cartan variables. In the present work we apply Wolfgang Kummer's philosophy, the 'Vienna School approach', to a specific three-dimensional model of gravity, cos-mological topologically massive gravity at the chiral point. Exploiting a new Chern–Simons representation we perfo...
متن کاملGeometric interpretation and classification of global solutions in generalized dilaton gravity.
Two dimensional gravity with torsion is proved to be equivalent to special types of generalized 2d dilaton gravity. E.g. in one version, the dilaton field is shown to be expressible by the extra scalar curvature, constructed for an independent Lorentz connection corresponding to a nontrivial torsion. Elimination of that dilaton field yields an equivalent torsionless theory, nonpolynomial in cur...
متن کاملA Note on Dilaton Gravity with Non–Smooth Potentials
Recent interest in brane world models motivates the investigation of generic first order dilaton gravity actions, with potentials having some non-smoothness. We consider two different types of δ-like contributions in the action and analyse their effects on the solutions. Furthermore a second source of non-smoothness arises due to the remaining ambiguities in the solutions in the separated smoot...
متن کاملConserved quasilocal quantities and general covariant theories in two dimensions.
General matterless–theories in 1+1 dimensions include dilaton gravity, Yang– Mills theory as well as non–Einsteinian gravity with dynamical torsion and higher power gravity, and even models of spherically symmetric d = 4 General Relativity. Their recent identification as special cases of ’Poisson–sigma–models’ with simple general solution in an arbitrary gauge, allows a comprehensive discussion...
