TY - JOUR T1 - Some Perturbation Problems on 2x2 Nonlinear Hyperbolic Conservation Laws JO - Journal of Partial Differential Equations VL - 3 SP - 245 EP - 259 PY - 1998 DA - 1998/11 SN - 11 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5568.html KW - 2 × 2 genuinely nonlinear strictly hyperbolic conservation laws KW - perturbed problem KW - elementary waves with interuction AB - We study in this paper the perturbation of elementary waves with interactions: overtaking of shock waves belonging to the same characteristic family and penetrating of a shock wave and a rarefaction wave belonging to the different characteristic family for 2 × 2 genuinely nonlinear strictly hyperbolic conservation laws. The entropy solutions for the perturbed problems are obtained by the Glimm's scheme.
