Decay of Positive Waves for $n \times n$ Hyperbolic Systems of Balance Laws
Paola Goatin 1, Laurent Gosse 2
(2004-01)

We prove Ole\u \i nik-type decay estimates for entropy solutions of $n\times n$ strictly hyperbolic systems of balance laws built out of a wave-front tracking procedure inside which the source term is treated as a nonconservative product localized on a discrete lattice.
