Lack of BV Bounds for Approximate Solutions to the p-system with Large Data
Alberto Bressan, Geng Chen, Qingtian Zhang
We consider front tracking approximate solutions to the p-system of isentropic gas dynamics. At interaction times, the outgoing wave fronts have the same strength as in the exact s…
