Application of invariants of characteristics to construction of solutions without gradient catastrophe

Alexander V. Aksenov, Konstantin P. Druzhkov, Oleg V. Kaptsov

The one-dimensional system of equations of isentropic gas dynamics is considered. First-order invariants of characteristics of this system are classified. Second-order invariants o…
