Lagrangian-Hamiltonian formalism for cocontact systems
In this paper we present a unified Lagrangian–Hamiltonian geometric formalism to describe
time-dependent contact mechanical systems, based on the one first introduced by K. Kamimura and
later formalized by R. Skinner and ...

Time-dependent contact mechanics
Contact geometry allows us to describe some thermodynamic and dissipative systems. In this paper we introduce a new geometric structure in order to describe time-dependent contact systems: cocontact manifolds. Within this ...
Estabilización de órbitas periódicas en hamiltonianos T-periódicos
(2019)
En este trabajo se pretende generalizar el método de control desarrollado por Leiva y Briozzo, a fin de hacerlo aplicable a la estabilización de órbitas periódicas inestables (OPIs) en Hamiltonianos periódicos en el tiempo, ...
Pseudoinvariance and the extra degree of freedom in f (T) gravity
(American Physical Society, 2020-04)
Nonlinear generalizations of teleparallel gravity entail the modification of a Lagrangian that is pseudoinvariant under local Lorentz transformations of the tetrad field. This procedure consequently leads to the loss of ...
Robust tori-like Lagrangian coherent structures
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In general the term "Lagrangian coherent structure" (LCS) is used to make reference about structures whose properties are similar to a time-dependent analog of stable and unstable manifolds from a hyperbolic fixed point ...
