Higher order curvature generalisations of Bartnick-McKinnon and coloured black hole solutions in
Yves Brihaye, A. Chakrabarti, Betti Hartmann +1
We construct globally regular as well as non-abelian black hole solutions of a higher order curvature Einstein-Yang-Mills (EYM) model in dimensions. This model consists of th…
Nonlinear transforms of momenta and Planck scale limit
A. Chakrabarti
Starting with the generators of the Poincaré group for arbitrary mass (m) and spin (s) a nonunitary transformation is implemented to obtain momenta with an absolute Planck scale li…
Spectral Decomposition and Baxterisation of Exotic Bialgebras and Associated Noncommutative Geometries
D. Arnaudon, A. Chakrabarti, V. K. Dobrev +1
We study the geometric aspects of two exotic bialgebras S03 and S14 introduced in math.QA/0206053. These bialgebras are obtained by the Faddeev-Reshetikhin-Takhtajan RTT prescripti…
Modified braid equations, Baxterizations and noncommutative spaces for the quantum groups and
A. Chakrabarti, R. Chakrabarti
Modified braid equations satisfied by generalized matrices (for a {\em given} set of group relations obeyed by the elements of matrices ) are constructed for q…
Duality and Representations for New Exotic Bialgebras
D. Arnaudon, A. Chakrabarti, V. K. Dobrev +1
We find the exotic matrix bialgebras which correspond to the two non-triangular nonsingular 4x4 R-matrices in the classification of Hietarinta, namely, R_{S0,3} and R_{S1,4}. We fi…
Non-factorisable metrics and Gauss--Bonnet terms in higher dimensions
B. Abdesselam, A. Chakrabarti, J. Rizos +1
An iterative construction of higher order Einstein tensors for a maximally Gauss-Bonnet extended gravitational Lagrangian was introduced in a previous paper. Here the formalism is…
Particle-like solutions to higher order curvature Einstein--Yang-Mills systems in d dimensions
Y. Brihaye, A. Chakrabarti, D. H. Tchrakian
We consider the superposition of the first two members of the gravitational hierarchy (Einstein plus first Gauss-Bonnet(GB)) interacting with the superposition of the first two mem…
