A Hamiltonian description of finite-time singularity in Euler's fluid equations
Philip J. Morrison, Yoshifumi Kimura
The recently proposed low degree-of-freedom model of Moffat and Kimura [1,2] for describing the approach to finite-time singularity of the incompressible Euler fluid equations is i…
A class of three-dimensional gyroviscous magnetohydrodynamic models
Manasvi Lingam, Philip J. Morrison, Alexander Wurm
A Hamiltonian and action principle formalism for deriving three-dimensional gyroviscous magnetohydrodynamic models is presented. The uniqueness of the approach in constructing the…
Lagrangian and Dirac constraints for the ideal incompressible fluid and magnetohydrodynamics
P. J. Morrison, T. Andreussi, F. Pegoraro
The incompressibility constraint for fluid flow was imposed by Lagrange in the so-called Lagrangian variable description using his method of multipliers in the Lagrangian (variatio…
Deformation of Lie-Poisson algebras and chirality
Zensho Yoshida, Philip J. Morrison
Linearization of a Hamiltonian system around an equilibrium point yields a set of Hamiltonian-symmetric spectra: If is an eigenvalue of the linearized generator, and $\bar…
