Black holes in generalized dilaton gravity in two dimensions

S. Mignemi

We consider two-dimensional dilaton-gravity theories with a generic exponential potential for the dilaton, and obtain the most general black hole solutions in the Schwarzshild form…

Non-singular four-dimensional black holes and the Jackiw-Teitelboim theory

M. Cadoni, S. Mignemi

A four-dimensional dilaton-gravity action whose spherical reduction to two dimensions leads to the Jackiw-Teitelboim theory is presented. A nonsingular black hole solution of the t…

Cosmological and Wormhole Solutions in Low-Energy Effective String Theory

Mariano Cadoni, Marco Cavaglia

We derive and study a class of cosmological and wormhole solutions of low-energy effective string field theory. We consider a general four-dimensional string effective action where…

Duality of Lorentzian and Euclidean black holes in two-dimensional string-generated models

M. Cadoni, S. Mignemi

We discuss the properties of lorentzian and euclidean black hole solutions of a generalized 2-dim dilaton-gravity action containing a modulus field, which arises from the compactif…

Classical and Semiclassical Properties of Extremal Black Holes with Dilaton and Modulus Fields

M. Cadoni, S. Mignemi

We discuss both classical and semiclassical properties of extremal black holes in theories where the dilaton and a modulus field are present. We find that the corresponding 2-dim g…
