Gravitational collapse in spatially isotropic coordinates

Megan Govender, Robert Bogadi, Ranjan Sharma +1

We investigate the dynamical nature of the collapse process of a spherically symmetric star in quasi-static hydrodynamical equilibrium. The star collapses from an initial static co…

Multi-Symplectic Magnetohydrodynamics

G. M. Webb, J. F. McKenzie, G. P. Zank

A multi-symplectic formulation of ideal magnetohydrodynamics (MHD) is developed based on a Clebsch variable variational principle in which the Lagrangian consists of the kinetic mi…

Application of Group Analysis to Classification of Systems of Three Second-Order Ordinary Differential Equations

S. Suksern, S. Moyo, S. V. Meleshko

Here we give a complete group classification of the general case of linear systems of three second-order ordinary differential equations excluding the case of systems which are stu…

Local and Nonlocal Advected Invariants and Helicities in Magnetohydrodynamics and Gas Dynamics I: Lie Dragging Approach

Gary M. Webb, Brahmananda Dasgupta, James F McKenzie +2

In this paper we discuss conservation laws in ideal magnetohydrodynamics (MHD) and gas dynamics associated with advected invariants. The invariants in some cases, can be related to…

Local and Nonlocal Advected Invariants and Helicities in Magnetohydrodynamics and Gas Dynamics II: Noether's Theorems and Casimirs

G. M. Webb, B. Dasgupta, J. F. McKenzie +2

Conservation laws in ideal gas dynamics and magnetohydrodynamics (MHD) associated with fluid relabelling symmetries are derived using Noether's first and second theorems. Lie dragg…
