Stability of inviscid shear shallow water flows with free surface is studied in the framework of the Benney equations. This is done by investigating the generalized hyperbolicity of the …
We present an infinite family of Hamiltonian electromagnetic fluid models for plasmas, derived from drift-kinetic equations. An infinite hierarchy of fluid equations is obtained from a …

The Hamiltonian structure for an infinite class of nonlinear reduced fluid models, derived from a Hamiltonian drift-kinetic system, is explicitly provided in terms of the N+ 1 fluid …

For an arbitrary number of species, we derive a Hamiltonian fluid model for strongly magnetized plasmas describing the evolution of the density, velocity, and electromagnetic …

Moment closures of the Vlasov-Ampère system, whereby higher moments are represented as functions of lower moments with the constraint that the resulting fluid system remains …
Kinetic theory describes a dilute monatomic gas using a distribution function f (q, p, t), the expected phase-space density of particles at a given position q with a given momentum p …

We consider the Vlasov–Maxwell equations with one spatial direction and two momenta. By solving the Jacobi identity, we derive reduced Hamiltonian fluid models for the density, the …
In this thesis, we study three applications of the noncanonical Hamiltonian formalism to fluid dynamics and the kinetic theory of gases and polymers. The first application is in polymer …
