Nonlinear theory for coalescing characteristics in multiphase Whitham modulation theory [PDF]

open access: yes, 2020
The multiphase Whitham modulation equations with $N$ phases have $2N$ characteristics which may be of hyperbolic or elliptic type. In this paper a nonlinear theory is developed for coalescence, where two characteristics change from hyperbolic to elliptic

The limit of vanishing viscosity for doubly nonlinear parabolic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
We show that solutions of the doubly nonlinear parabolic equation \begin{equation*} \frac{\partial b(u)}{\partial t} - \epsilon \operatorname{div}(a(\nabla u)) + \operatorname{div}(f(u)) = g \end{equation*} converge in the limit $\epsilon ...
