Asymptotic analysis of the Skyrmed monopole
Y. Brihaye, J. Burzlaff, D. H. Tchrakian
We consider a variant of the Georgi Glashow model in the BPS limit, augmented by a higher derivative Skyrme-like term, which is the simplest YMH model that can support monopole bou…
Spherically symmetric selfdual Yang-Mills instantons on curved backgrounds in all even dimensions
Eugen Radu, D. H. Tchrakian, Yisong Yang
We present several different classes of selfdual Yang-Mills instantons in all even d backgrounds with Euclidean signature. In d=4p+2 the only solutions we found are on constant cur…
AdS rotating non-Abelian black holes
Y. Brihaye, E. Radu, D. H. Tchrakian
We present arguments for the existence of charged, rotating black holes with equal magnitude angular momenta in Einstein-Yang-Mills theory with negative cosmological constant…
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…
Antisymmetrised 2p-forms generalising curvature 2-forms II: a p-hierarchy of Reissner-Nordstrom type metrics in dimensions d>2p+1
A. Chakrabarti, D. H. Tchrakian
The p-hierarchy of Schwarzschild type metrics obtained in a preceing paper is generalised here to a corresponding Reissner-Nordstrom (RN) type hierarchy in the presence of a point…
Antisymmetrised 2p-forms generalising curvature 2-forms and a corresponding p-hierarchy of Schwarzschild type metrics in dimensions d>2p+1
A. Chakrabarti, D. H. Tchrakian
Starting with the curvature 2-form a recursive construction of totally antisymmetrised 2p-forms is introduced, to which we refer as p-Riemann tensors. Contraction of indices permit…
