Analysis of a Spacetime Discontinuous Galerkin Method for Systems of Conservation Laws
… naturally suggests a discrete version of the Lax entropy condition. The CSDG method is an explicit method, that is, a direct element-by-element solution procedure is possible. We investigate existence, uniqueness and continuous dependence on the initial data of a CSDG solution for general …

Transient Electromagnetic Waves in Nonlinear Media
… to be stable, they must satisfy a number of conditions, similar to Lax's classical shock conditions. These conditions permit us to classify electromagnetic shock waves as slow, fast or intermediate shock waves. Finally, Paper V investigates the uniqueness and continuous dependence on data for …

Viscous fingering instabilities and gravity currents.–—
… of a small density difference yields an Oleinik entropy condition, which predicts a unique shock height for the self-similar base state. The subsequent linear stability analysis reveals many similarities to Hele-Shaw flows, in particular the singular nature of large azimuthal wavenumbers. …
