摘要

在本文中，我们证明了一类广义的$2\times2$对称双曲系统的局部（在时间上）适定性，该系统包含额外的非局部项。最新结果暗示了Clamond等人[2]引入的底部不均匀的Saint-Venant系统的非色散正则化的局部适定性。我们还证明了，只要一阶导数是有界的，奇点就不会出现。

Local well-posedness of a Hamiltonian regularisation of the Saint-Venant system with uneven bottom

We prove in this note the local (in time) well-posedness of a broad class of $2 \times 2$ symmetrisable hyperbolic system involving additional non-local terms. The latest result implies the local well-posedness of the non dispersive regularisation of the Saint-Venant system with uneven bottom introduced by Clamond et al. [2]. We also prove that, as long as the first derivatives are bounded, singularities cannot appear.
