We establish two-loop (on-shell) finiteness of certain supergravity theories in two dimensions. Possible implications of this result are discussed. 
Two two-dimensional supergravity theories from Calabi–Yau four-folds
We consider two-dimensional supergravity theories with four supercharges constructed from compactification of Type II string theory on a generic Calabi–Yau four-fold. In type IIA and type IIB cases,Expand
On N=1 4d Effective Couplings for F-theory and Heterotic Vacua
We show that certain superpotential and Kahler potential couplings of N=1 supersymmetric compactifications with branes or bundles can be computed from Hodge theory and mirror symmetry. This appliesExpand
Type IIA and heterotic string vacua in D=2 ? ? Work supported by: DFG The German Science Foundatio
Abstract We study type IIA string theory compactified on Calabi–Yau fourfolds and heterotic string theory compactified on Calabi–Yau threefolds times a two-torus. We derive the resulting effectiveExpand
U-duality twists and possible phase transitions in 2+1 D supergravity
We study 2+1D toroidal compactifications of M-theory with twists in the U-duality group. These compactifications realize many symmetric-manifolds from the classification of 2+1D extended supergravityExpand
New linear systems for 2d Poincaré supergravities
Abstract A new linear system is constructed for Poincare supergravities in two dimensions. In contrast to previous results, which were based on the conformal gauge, this linear system involves theExpand
Locally supersymmetric D = 3 non-linear sigma models
Abstract We study non-linear sigma models with N local supersymmetries in three space-time dimensions. For N = 1 and 2 the target space of these models is riemannian or Kahler, respectively. All N >Expand
A class of finite two-dimensional sigma models and string vacua
Abstract We consider a two-dimensional Minkowski signature sigma model with a (2 + N )-dimensional target space metric having a null Killing vector. It is found that the model is finite to all ordersExpand
On the renormalization of truncated quantum Einstein gravity
The perturbative renormalizability of the 2-Killing vector reduction of general relativity is investigated. Although non-renormalizable in the standard sense, we show that to all orders of the loopExpand

Abstract We consider a two-dimensional sigma model with a (2 + N)-dimensional Minkowski signature target space metric having a covariantly constant null Killing vector. We study solutions of theExpand

TLDR
A gauge theory of two-dimensional gravity which is derived from a generalization of the Jackiw-Teitelboim model is presented and the exact quantum solution of this model is constructed using canonical quantization. Expand

Abstract Classes of anomalous two-dimensional theories are solved. In physical gauges the spectrum is not relativistic. Anomalous models in covariant gauges are equivalent to adding Wess-Zumino termsExpand

Inspired by the recent work of Knizhnik, Polyakov and Zamolodchikov on the 2D quantum gravity in the “light cone” gauge, we present a proposal for solving the theory in the usual conformal gauge. OurExpand
Are the stationary, axially symmetric Einstein equations completely integrable?
A linear eigenvalue problem in the spirit of Lax is constructed for the stationary, axially symmetric Einstein equations. It is conjectured that this entails the complete integrability of the system.
