含时空白噪声的次控制准地转方程

Paracontrolled quasi-geostrophic equation with space-time white noise

Yuzuru Inahama, Yoshihiro Sawano

摘要:

研究了二维环面上带时空白噪声的随机耗散准地转方程。这个方程是高度奇异的,在其原始形式下基本上是不适定的。本文的主要目的是制定和解决这个方程的局部时间的框架下的paracontrolled微积分的微分阶的主要条款,分数拉普拉斯,是大于$7/4$。这个模型不需要重正化。

英文摘要:

We study the stochastic dissipative quasi-geostrophic equation with space-time white noise on the two-dimensional torus. This equation is highly singular and basically ill-posed in its original form. The main objective of the present paper is to formulate and solve this equation locally in time in the framework of paracontrolled calculus when the differential order of the main term, the fractional Laplacian, is larger than $7/4$. No renormalization has to be done for this model.
