Jacobi equations of geodetic brane gravity
Riccardo Capovilla, Giovany Cruz, Efraín Rojas
We consider brane gravity as described by the Regge-Teitelboim geometric model, in any codimension. In brane gravity our spacetime is modeled as the time-like world volume spanned…
Ostrogradsky-Hamilton approach to geodetic brane gravity
Riccardo Capovilla, Giovany Cruz, Efraín Rojas
We develop the Ostrogradsky-Hamilton formalism for geodetic brane gravity, described by the Regge-Teitelboim geometric model in higher codimension. We treat this gravity theory as…
Hamilton-Jacobi approach for linearly acceleration-dependent Lagrangians
Alejandro Aguilar-Salas, Efraín Rojas
We develop a constructive procedure for arriving at the Hamilton-Jacobi framework for the so-called affine in acceleration theories by analysing the canonical constraint structure.…
Hamiltonian dynamics of gonihedric string theory
Alberto Molgado, Efrain Rojas
We develop in a consistent manner the Ostrogradski-Hamilton framework for gonihedric string theory. The local action describing this model, being invariant under reparametrizations…
Hamilton-Jacobi approach for Regge-Teitelboim cosmology
Alejandro Aguilar-Salas, Alberto Molgado, Efrain Rojas
The Hamilton-Jacobi formalism for a geodetic brane-like universe described by the Regge-Teitelboim model is developed. We focus on the description of the complete set of Hamiltonia…
Stealth's cosmologies
Abigail Alvarez, Cuauhtemoc Campuzano, Víctor Cárdenas +1
We present a novel approach to construct cosmological models endowed with a particular scalar field, the stealth. The model is constructed by studying a scalar field no-minimally c…
