Simulation of two-dimensional high reynolds number wake flows with the use of filtered lagrangian navier-stokes equations
(2011)
This work presents a method for numerical simulation of viscous fluid flows based on the use of filtered Lagrangian Navier-Stokes equations. It is based on the hypothesis that the small scale motions are responsible for ...
Lagrangian Formulation, Generalizations and Quantization of Null Maxwell's Knots
(2018-08-01)
Knotted solutions to electromagnetism are investigated as an independent subsector of the theory. We write down a Lagrangian and a Hamiltonian formulation of Bateman's construction for the knotted electromagnetic solutions. ...

GPGPU implementation of the BFECC algorithm for pure advection equations
(Springer, 2013-11-27)
In the present work an implementation of the Back and Forth Error Compensation and Correction (BFECC) algorithm specially suited for running on General-Purpose Graphics Processing Units (GPGPUs) through Nvidia`s Compute ...
Lagrangian Formulations to Solve Free Surface Incompressible Fluid Flows
(Elsevier Science Sa, 2001-12)
A particle method is presented for the solution of the incompressible inviscid fluid flow equation using a Lagrangian formulation. The interpolated function are those used in ``meshless´´ approximations and the time ...
A universal order parameter for Inverse Magnetic Catalysis
(Springer, 2017-10-05)
We revisit the chiral transition in the finite density Sakai-Sugimoto model and find that, at fixed temperature T, the magnetisation near the critical line mu(c)(B) acts as an order parameter to distinguish Inverse Magnetic ...
COMPARISON RESULTS FOR CONJUGATE AND FOCAL POINTS IN SEMI-RIEMANNIAN GEOMETRY VIA MASLOV INDEX
(PACIFIC JOURNAL MATHEMATICS, 2009)
We prove an estimate on the difference of Maslov indices relative to the choice of two distinct reference Lagrangians of a continuous path in the Lagrangian Grassmannian of a symplectic space. We discuss some applications ...
