We approach the subject in two different ways. The first way is by perturbing the system with a small pressure term. The obtained perturbed system is strictly hyperbolic. We use the new bounds on the strength of elementary waves in the Wave Front Tracking algorithm. That allows us to get a global solution for initial data with arbitrary large total variation, provided that the perturbing parameter is small enough. The second approach is by using a shadow wave solution concept. The paper ends with the comparison of the solutions obtained in these two ways. | URI: | https://open.uns.ac.rs/handle/123456789/28242 | ISSN: | 0022-247X |
