Hidden symmetries in minimal five-dimensional supergravity
Markus Pössel, Sebastian Silva
We study the hidden symmetries arising in the dimensional reduction of d=5, N=2 supergravity to three dimensions. Extending previous partial results for the bosonic part, we give a…
Are there really any AdS_2 branes in the euclidean (or not) AdS_3?
Benedicte Ponsot, Sebastian Silva
We do not find any AdS_2 branes, neither in the H_3^+ WZNW model nor the SL(2,R) WZNW model. We then reexamine the case of the branes that possess a su(2) symmetry: we speculate th…
On covariant phase space methods
Bernard Julia, Sebastian Silva
It is well known that the Lagrangian and the Hamiltonian formalisms can be combined and lead to "covariant symplectic" methods. For that purpose a "pre-symplectic form" has been co…
Brane-World charges
Sebastian Silva
As opposed to usual Einstein gravity in four dimensions, the Brane-World scenario allows the construction of a local density of gravitational energy (and also of momentum, of angul…
