TY - JOUR T1 - Life-span of Classical Solutions of Nonlinear Hyperbolic Systems JO - Journal of Partial Differential Equations VL - 3 SP - 221 EP - 236 PY - 1996 DA - 1996/09 SN - 9 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5623.html KW - Nonlinear hyperbolic system KW - Cauchy problem KW - life-span AB - In this paper, we give a lower bound for the life-span of classical solutions to the Cauchy problem for first order nonlinear hyperbolic systems with small initial data, which is sharp, and give its application to the system of one-dimensional gas dynamics; for the Cauchy problem of the system of one-dimensional gas dynamics with a kind of small oscillatory initial data, we obtain a precise estimate for the life-span of classical solutions.
