Abstract

The numerical calculation of shock wave by the Euler equations can generate in some cases and with some numerical schemes a pathology: it is the so-called carbuncle phenomenon. The purpose of this paper is to show that this pathology can be interpreted by the existence of an unstable mode in the continuous Euler equations.
