Characterization of extrasolar planetary transiting candidates II
J. Gallardo, S. Silva, S. Ramirez Alegria +2
We present a second paper of fully characterization of a sample of stars whose low-depth transits were discovered by the OGLE-III campaign in order to select the most promising can…
Noether superpotentials in supergravities
M. Henneaux, B. Julia, S. Silva
Straightforward application of the standard Noether method in supergravity theories yields an incorrect superpotential for local supersymmetry transformations, which gives only hal…
On Superpotentials and Charge Algebras of Gauge Theories
S. Silva
We propose a new "Hamiltonian inspired" covariant formula to define (without harmful ambiguities) the superpotential and the physical charges associated to a gauge symmetry. The cr…
Currents and Superpotentials in classical gauge invariant theories I. Local results with applications to Perfect Fluids and General Relativity
B. Julia, S. Silva
E. Noether's general analysis of conservation laws has to be completed in a Lagrangian theory with local gauge invariance. Bulk charges are replaced by fluxes of superpotentials. G…
