Viscous boundary layers in hyperbolic-parabolic systems with Neumann boundary conditions
Olivier Gues, Guy Metivier, Mark Williams +1
We initiate the study of noncharacteristic boundary layers in hyperbolic-parabolic problems with Neumann boundary conditions. More generally, we study boundary layers with mixed Di…
Semilinear geometric optics with boundary amplification
Jean-Francois Coulombel, Olivier Guès, Mark Williams
We study weakly stable semilinear hyperbolic boundary value problems with highly oscillatory data. Here weak stability means that exponentially growing modes are absent, but the so…
Singular pseudodifferential calculus for wavetrains and pulses
Jean-Francois Coulombel, Olivier Guès, Mark Williams
We develop a singular pseudodifferential calculus. The symbols that we consider do not satisfy the standard decay with respect to the frequency variables. We thus adopt a strategy…
