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…

Schwarzschild Spacetime without Coordinates
Orlando Alvarez
We discuss how to construct the full Schwarzschild (Kruskal-Szekeres) spacetime in one swoop by using the bundle of orthonormal Lorentz frames and the Einstein equation without the…
