Exact correlators of two-matrix models
Abstract We compute exact solutions of two-matrix models, i.e. detailed genus by genus expressions for the correlation functions of these theories, calculated without any approximation. WeExpand

Electrically Charged Cold Black Holes in Scalar-Tensor Theories
We study the possible existence of charged black holes in the Bergmann–Wagoner class of scalar-tensor theories (STT) of gravity in four dimensions. The existence of black holes is shown for anomalousExpand

Construction of exact Riemannian instanton solutions
We present the exact construction of Riemannian (or stringy) instantons, which are classical solutions of 2D Yang–Mills theories that interpolate between initial and final string configurations. TheyExpand

Quantization of Lorentzian 3D gravity by partial gauge fixing
D = 2 + 1 gravity with a cosmological constant Λ has been shown by Bonzom and Livine to present a Barbero–Immirzi-like ambiguity depending on a parameter γ. We make use of this fact to show that, forExpand

Structure and stability of cold scalar-tensor black holes
Abstract We study the structure and stability of the recently discussed spherically symmetric Brans-Dicke black-hole type solutions with an infinite horizon area and zero Hawking temperature,Expand

Cold scalar-tensor black holes: causal structure, geodesics, stability.
We study the structure and stability of spherically symmetric Brans-Dicke black-hole type solutions with an infinite horizon area and zero Hawking temperature, existing for negative values of theExpand

Quantization of the Jackiw-Teitelboim model
We study the phase space structure of the Jackiw-Teitelboim model in its connection variables formulation where the gauge group of the field theory is given by local SL(2,R)[or SU(2) for theExpand

Higher spin symmetries and w∞ algebra in the conformal affine Toda model
Abstract As recently shown the conformal affine Toda models can be obtained via hamiltonian reduction from a two-loop Kac-Moody algebra. In this paper we propose a systematic procedure to analyze theExpand

Direct test of the integral Yang-Mills equations through S U (2 ) monopoles
We use the SU(2) 't Hooft-Polyakov monopole configuration, and its BPS version, to test the integral equations of the Yang-Mills theory. Those integral equations involve two (complex) parametersExpand
