Local well-posedness in the problem of ow about in nite plane wedge with inviscous non-heat-conducting gas

We study the problem for a supersonic stationary van der Waals gas flow onto a planar infinite wedge. For the case when the basic solution is a weak shock wave, i.e. the gas velocity behind the shock front is supersonic, we prove the local-in-time well-posedness of the corresponding nonstationary problem.
