Peng, Yue-Jun Life- span of classical solutions to the gas dynamics equations. (Temps de vie de solutions classiques pour la dynamique des gaz.) (French) Zbl 0813.76076 C. R. Acad. Sci., Paris, Sér. I 319, No. 5, 451-454 (1994). Summary: We establish an estimation of life-span for the regular solution to Cauchy problem for gas dynamics equations, the initial data are taken as a small perturbation of a particular solution. This estimation shows that the classical solution persists in a very large time interval.
