Yang-Mills model for centrally extended 2d gravity
Sara Abentin, Fernando Ruiz Ruiz
A Yang-Mills theory linear in the scalar curvature for 2d gravity with symmetry generated by the semidirect product formed with the Lie derivative of the algebra of diffeomorphisms…
Perturbative quantization of Yang-Mills theory with classical double as gauge algebra
F. Ruiz Ruiz
Perturbative quantization of Yang-Mills theory with a gauge algebra given by the classical double of a semisimple Lie algebra is considered. The classical double of a real Lie alge…
Yang-Mills theory for semidirect products and its instantons
F. Ruiz Ruiz
Yang-Mills theory with a symmetry algebra that is the semidirect product defined by the coadjoint action of a Lie algebra on its…
D-branes with Lorentzian signature in the Nappi-Witten model
R. Hernandez, G. Horcajada, F. Ruiz Ruiz
Lorentzian signature D-branes of all dimensions for the Nappi-Witten string are constructed. This is done by rewriting the gluing condition for the model chiral currents…
Geometric construction of D-branes in WZW models
G. Horcajada, F. Ruiz Ruiz
The geometric description of D-branes in WZW models is pushed forward. Our starting point is a gluing condition\, that matches the model's chiral currents at the world…
Seiberg--Witten maps for gauge invariance and deformations of gravity
S. Marculescu, F. Ruiz Ruiz
A family of diffeomorphism-invariant Seiberg--Witten deformations of gravity is constructed. In a first step Seiberg--Witten maps for an SO(1,3) gauge symmetry are obtained for con…
