粘弹性介质中短波长波相互作用的非线性模型

A nonlinear model describing a short wave long wave interaction in a viscoelastic medium

Paulo Amorim, João-Paulo Dias

摘要:

在本文中,我们介绍了一个系统耦合的非线性薛定谔方程的粘弹性系统,模拟短波和长波之间的相互作用,例如对介质,如等离子体或聚合物。我们证明了相应的Cauchy问题的局部(在时间上)强解的存在唯一性和整体弱解的存在性.特别地,我们推广了[Nohel \emph{et. al.},Commun.部分Diff.等式,13(1988)]的粘弹性准线性系统。最后,我们用一些数值计算来说明我们的结果。

英文摘要:

In this paper we introduce a system coupling a nonlinear Schrödinger equation with a system of viscoelasticity, modeling the interaction between short and long waves, acting for instance on media like plasmas or polymers. We prove the existence and uniqueness of local (in time) strong solutions and the existence of global weak solutions for the corresponding Cauchy problem. In particular we extend previous results in [Nohel \emph{et. al.}, Commun. Part. Diff. Eq., 13 (1988)] for the quasilinear system of viscoelasticity. We finish with some numerical computations to illustrate our results.
