A Hamilton-Jacobi Theory for Singular Lagrangian Systems in the Skinner and Rusk Setting
Hamilton-Jacobi theory presymplectic constraint algorithm
font style='font-size:12px;'>
2012/5/9
We develop a Hamilton-Jacobi theory for singular lagrangian systems in the Skinner-Rusk formalism. Comparisons with the Hamilton-Jacobi problem in the lagrangian and hamiltonian settings are discussed...
Local BRST cohomology in (non-)Lagrangian field theory
Local BRST cohomology (non-)Lagrangian field theory Quantum Algebra

2011/7/29
Abstract: Some general theorems are established on the local BRST cohomology for not necessarily Lagrangian gauge theories. Particular attention is given to the BRST groups with direct physical interp...
Lagrangian-Hamiltonian unified formalism for autonomous higher-order dynamical systems
Higher-order systems Lagrangian and Hamiltonian formalisms Symplectic and presymplectic manifolds
font style='font-size:12px;'>
2011/7/26
Abstract: The Lagrangian-Hamiltonian unified formalism of R. Skinner and R. Rusk was originally stated for autonomous dynamical systems in classical mechanics. It has been generalized for non-autonomo...
Conditional Eulerian and Lagrangian velocity increment statistics of fully developed turbulent flow
Lagrangian velocity increment statistics fully developed turbulent flow
font style='font-size:12px;'>
2010/11/16
Conditional statistics of homogeneous isotropic turbulent flow is investigated by means of high-Reynolds number direct numerical simulations performed with $2048^3$ collocation points. Eulerian as we...
Regular hyperbolicity, dominant energy condition and causality for Lagrangian theory of maps
Regular hyperbolicity dominant energy condition causality for Lagrangian theory of maps

2010/12/21
The goal of the present paper is three-fold. First is to clarify the connection between the dominant energy condition and hyperbolicity properties of Lagrangian field theories.
Trajectories and Stability Regions of the Lagrangian Point $L_1$ in the Generalized Chermnykh-Like Problem
Trajectories $L_1$ Chermnykh-Like Problem
font style='font-size:12px;'>
2010/4/6
The Lagrange point $L_1$ for the Sun-Earth system is considered due to its special importance for the scientific community for the design of space missions. The location of the Lagrangian points with ...
On Lagrangian and Hamiltonian systems with homogeneous trajectories
Hamiltonian systems homogeneous trajectories
font style='font-size:12px;'>
2010/4/6
Motivated by various results on homogeneous geodesics of Riemannian spaces, we study homogeneous trajectories, i.e. trajectories which are orbits of a one-parameter symmetry group, of Lagrangian and H...
Lagrangian transport and chaos in the near wake of the flow around an obstacle:a numerical implementation of lobe dynamics
Lagrangian transport near wake numerical implementation lobe dynamics
font style='font-size:12px;'>
2009/11/13
In this paper we study Lagrangian transport in the near wake of the flow around an obstacle, which we take to be a cylinder. In this case, for the range of Reynolds numbers investigated, the flow is t...
