A general BV existence result for conservation laws with spatial heterogeneities

Résumé

We consider a scalar conservation law with a flux containing spatial heterogeneities of bounded variation, where the number of discontinuities may be infinite. We prove existence of an adapted entropy solution in the sense of Audusse-Perthame in the BV framework, under the assump- tions that guarantee uniqueness of the solution, plus one additional technical assumption. We prove that existence in the BV framework fails withouth this additional technical assumption, by providing a counter-example.
