Gravitational Cheshire effect: Nonminimally coupled scalar fields may not curve spacetime
Eloy Ayón-Beato, Cristián Martínez, Ricardo Troncoso +1
It is shown that flat spacetime can be dressed with a real scalar field that satisfies the nonlinear Klein-Gordon equation without curving spacetime. Surprisingly, this possibility…
11D Supergravity as a gauge theory for the M-algebra
Mokhtar Hassaine, Ricardo Troncoso, Jorge Zanelli
The eleven-dimensional gravitational action invariant under local Poincare transformations is given by the dimensional continuation of the Euler class of ten dimensions. Here we sh…
Vacuum Energy in Odd-Dimensional AdS Gravity
P. Mora, R. Olea, R. Troncoso +1
A background-independent, Lorentz-covariant approach to compute conserved charges in odd-dimensional AdS gravity, alternative to the standard counterterms method, is presented. A s…
Irregular Hamiltonian Systems
Olivera Miskovic, Jorge Zanelli
Hamiltonian systems with linearly dependent constraints (irregular systems), are classified according to their behavior in the vicinity of the constraint surface. For these systems…
(Super)-Gravities Beyond 4 Dimensions
Jorge Zanelli
These lectures are intended as a broad introduction to Chern Simons gravity and supergravity. The motivation for these theories lies in the desire to have a gauge invariant action…
