En este trabajo analizamos la teoría de lentes gravitaciones débiles sobre un background plano. Obtenemos expresiones concretas para los escalares ópticos a segundo orden en la perturbación de la métrica plana de forma ...

The different roles played by Lorentz connections in general relativity and in teleparallel gravity are reviewed. Some of the consequences of this difference are discussed.

We report results concerning the treatment of elastic bodies described by implicit constitutive relations which are not solvable, in the sense of expressing the stresses as functions of the strains or vice versa. Motivated ...

A Process Manual. Contains the diagrammed flows of activities, sub processes and processes that make up Macroprocess 4 Institutional and Diplomatic Relations.

We analyzed the constraint structure of the Einstein-Hilbert first-order action in two dimensions using the Hamilton-Jacobi approach. We were able to find a set of involutive, as well as a set of non-involutive constraints. ...
