They go back to Nishida [39] for the compressible Euler equation (this is a local in time result) and this type of proof was also developed for the incompressible Navier-Stokes

While a local existence theorem has already been proven in any dimension for the Abv model, we get interested in this paper in the one-dimensional case, where we prove the existence
