Title: Global solution and singularity formation for the supersonic expanding wave of compressible Euler equations with radial symmetry
(Submitted on 11 Apr 2024 (v1), last revised 26 Apr 2024 (this version, v2))
Abstract: In this paper, we define the rarefaction and compression characters for the supersonic expanding wave of the compressible Euler equations with radial symmetry. Under this new definition, we show that solutions with rarefaction initial data will not form shock in finite time, i.e. exist global-in-time as classical solutions. On the other hand, singularity forms in finite time when the initial data include strong compression somewhere. Several useful invariant domains will be also given.
