The stability of compressible vortex sheets in two space dimensions. (English) Zbl 1068.35100
The paper deals with vortex sheets, i.e, velocity discontinuities in an inviscid flow, in the compressible case, in two spaces dimensions. An energy estimate for the linearized boundary value problem is proved. Since the problem is characteristic, the estimate exhibits a loss of control on the trace of the solution. Furthermore, the failure of the uniform Kreiss-Lopatinskii condition yields a loss of derivatives in the energy estimate.
