随机噪声作用下三维磁流体动力学系统定律的非唯一性

Non-uniqueness in law of three-dimensional magnetohydrodynamics system forced by random noise

Kazuo Yamazaki

摘要:

我们证明了三维磁流体动力学系统的非唯一性的法律,被迫由随机噪声的添加剂和线性乘法型,并具有粘性和磁扩散,这两者都是弱于一个完整的拉普拉斯算子。我们将凸积分应用于速度方程和磁场方程,以获得在概率强解类中的非唯一律。

英文摘要:

We prove non-uniqueness in law of the three-dimensional magnetohydrodynamics system that is forced by random noise of an additive and a linear multiplicative type and has viscous and magnetic diffusion, both of which are weaker than a full Laplacian. We apply convex integration to both equations of velocity and magnetic fields in order to obtain the non-uniqueness in law in the class of probabilistically strong solutions.
