A note on the Hamiltonian structure of transgression forms
Pablo Pais, Patricio Salgado-Rebolledo, Aldo Vera
By incorporating two gauge connections, transgression forms provide a generalization of Chern-Simons actions that are genuinely gauge-invariant on bounded manifolds. In this work,…
Meronic Einstein-Yang-Mills black hole in 5D and gravitational spin from isospin effect
Fabrizio Canfora, Andrés Gomberoff, Seung Hun Oh +2
We construct an analytic black hole solution in Einstein-Yang-Mills theory in five dimensions supporting a Meron field. The gauge field is proportional to a pure gauge and…
Gravitational catalysis of merons in Einstein-Yang-Mills theory
Fabrizio Canfora, Seung Hun Oh, Patricio Salgado-Rebolledo
We construct regular configurations of the Einstein-Yang-Mills theory in various dimensions. The gauge field is of meron-type: it is proportional to a pure gauge (with a suitable p…
Supersymmetric 3D model for gravity with gauge symmetry, mass generation and effective cosmological constant
Pedro D. Alvarez, Pablo Pais, Eduardo Rodríguez +2
A Chern--Simons system in dimensions invariant under local Lorentz rotations, gauge transformations, and local supersymmetry transformations is propos…
Gribov ambiguity and degenerate systems
Fabrizio Canfora, Fiorenza de Micheli, Patricio Salgado-Rebolledo +1
The relation between Gribov ambiguity and degeneracies in the symplectic structure of physical systems is analyzed. It is shown that, in finite-dimensional systems, the presence of…
The BTZ black hole as a Lorentz-flat geometry
Pedro D. Alvarez, Pablo Pais, Eduardo Rodriguez +2
It is shown that 2+1 dimensional anti-de Sitter spacetimes are Lorentz-flat. This means, in particular, that any simply-connected patch of the BTZ black hole solution can be endowe…
Gribov gap equation at finite temperature
Fabrizio Canfora, Pablo Pais, Patricio Salgado-Rebolledo
In this paper the Gribov gap equation at finite temperature is analyzed. The solutions of the gap equation (which depend explicitly on the temperature) determine the structure of t…
Generalized Hedgehog ansatz and Gribov copies in regions with non trivial topologies
Fabrizio Canfora, Patricio Salgado-Rebolledo
In this paper the arising of Gribov copies both in Landau and Coulomb gauges in regions with non-trivial topologies but flat metric, (such as closed tubes S1XD2, or RXT2) will be a…
