Black Holes Without Coordinates
Orlando Alvarez
These lectures describe how to study the geometry of some black holes without the use of coordinates.
Integrable theories and loop spaces: fundamentals, applications and new developments
Orlando Alvarez, L. A. Ferreira, J. Sanchez-Guillen
We review our proposal to generalize the standard two-dimensional flatness construction of Lax-Zakharov-Shabat to relativistic field theories in d+1 dimensions. The fundamentals fr…
Target Space Duality III: Potentials
Orlando Alvarez, Blazej Ruszczycki
We generalize previous results on target space duality to the case where there are background fields and the sigma model lagrangian has a potential function.
Target Space Duality: The Dilaton Field
Orlando Alvarez, Blazej Ruszczycki
Classical target space duality transformations are studied for the non-linear sigma model with a dilaton field. Working within the framework of the Hamiltonian formalism we require…
