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…
Construction of Affine and Conformal Affine Toda Solitons by Hirota's Method
H. Aratyn, C. P. Constantinidis, L. A. Ferreira +2
In this talk we report some results about the construction of soliton solutions for the Affine and Conformal Affine Toda models using the Hirota's method. We obtain new classes of…
