Shock Reflection-Diffraction and Nonlinear Partial Differential Equations of Mixed Type

Abstract

We present our recent results on the existence and regularity of shock reflectiondiffraction configurations by a wedge up to the sonic wedge angle, which is the von Neumann sonic conjecture. The problem is first formulated as a boundary value problem for a second-order nonlinear partial differential equation of mixed hyperbolic-elliptic type in an unbounded… (More)
