The drift-wave dispersion equation revisited

Journal of Plasma Physics, 1993
In view of some difficulties that appeared in previous work, the drift-wave dispersion equation has been studied in great detail by stressing some features that are not discussed in the usual textbook presentations. It is shown that any analytical approximation of a plasma dispersion equation leads to a singular perturbation problem for the roots of an

Thermodynamics of Taylor dispersion: Constitutive equations

Physical Review E, 1993
This paper shows that the Taylor dispersion flux is a dissipative flux of extended thermodynamics. Every term in the evolution equations for the Taylor flux components is connected to a thermodynamic function and the entropy production is proved to be positive definite. Thermodynamic restrictions on phenomenological coefficients are also satisfied.

On nonlinear dispersive equations

1998
The author describes some of the recent developments in the application of harmonic analysis to nonlinear dispersive equations \[ u_t= iP(\nabla_x)u+ F(u)\;(t\in\mathbb{R},\;x\in\mathbb{R}^n) \] with initial data \(u(0,x)= u_0(x)\), where \(P(\nabla_x)\) is a differential operator with constant coefficients, \(F(u)\) represents nonlinearity.
