SL(2,R)-geometric phase space and (2+2)-dimensions
R. Flores, J. A. Nieto, J. Tellez +2
We propose an alternative geometric mathematical structure for arbitrary phase space. The main guide in our approach is the hidden SL(2,R)-symmetry which acts on the phase space ch…
Higher dimensional black holes as constrained systems
J. A. Nieto, E. A. Leon, V. M. Villanueva
We construct a Lagrangian and Hamiltonian formulation for charged black holes in a d-dimensional maximally symmetric spherical space. By considering first new variables that give r…
Higher Dimensional Cosmology: Relations among the radii of two homogeneous spaces
E. A. Leon, J. A. Nieto, R. Nunez-Lopez +1
We study a cosmological model in 1+D+d dimensions where D dimensions are associated with the usual Friedman-Robertson-Walker type metric with radio a(t) and d dimensions correspond…
Higher Dimensional Gravity and Farkas Property in Oriented Matroid Theory
J. A. Nieto, E. A. Leon
We assume gravity in a -dimensional manifold and consider a splitting of the form , with . The most general two-block metric associated with $M_{…
2D Gravity with Torsion, Oriented Matroids and 2+2 Dimensions
J. A. Nieto, E. A. Leon
We find a link between oriented matroid theory and 2d gravity with torsion. Our considerations may be useful in the context of noncommutative phase space in a target spacetime of s…
Issues of duality in Abelian Gauge Theory and in Linearized Gravity
J. A. Nieto, E. A. Leon
We start by describing two of the main proposals for duality in Abelian gauge theories, namely (ield strength)-duality approach and the % -duality formalism. We then discuss…
