Canonical Analysis of the Jackiw-Teitelboim Model in the Temporal Gauge. I. The Classical Theory
Clisthenis P. Constantinidis, Jose Andre Lourenco, Ivan Morales +2
As a preparation for its quantization in the loop formalism, the 2-dimensional gravitation model of Jackiw and Teitelboim is analysed in the classical canonical formalism. The dyna…
Regularity and stability of electrostatic solutions in Kaluza-Klein theory
M. Azreg-Ainou, G. Clement, C. P. Constantinidis +1
We investigate the family of electrostatic spherically symmetric solutions of the five-dimensional Kaluza-Klein theory. Besides black holes and wormholes, a new class of geodesical…
Cold Scalar-Tensor Black Holes: Causal Structure, Geodesics, Stability
K. A. Bronnikov, G. Clement, C. P. Constantinidis +1
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 negativ…
Cold black holes in scalar-tensor theories
K. A. Bronnikov, C. P. Constantinidis, R. L. Evangelista +1
We study the possible existence of black holes in scalar-tensor theories of gravity in four dimensions. Their existence is verified for anomalous versions of these theories, with a…
