%0 Journal Article %T Long-time behavior in scalar conservation laws %A Arnaud Debussche %A Julien Vovelle %J Mathematics %D 2008 %I arXiv %X We consider the long-time behavior of the entropy solution of a first-order scalar conservation law on a Riemannian manifold. In the case of the Torus, we show that, under a weak property of genuine non-linearity of the flux, the solution converges to its average value in $L^{p}$, $1\leq p<+\infty$. We give a partial result in the general case. %U http://arxiv.org/abs/0812.3537v1
