摘要:
本文主要讨论一类分式颜色噪声驱动的随机Burgers方程,其中时间是分式的,参数h∈(1/2,1),空间为协变差函数。 文章介绍了一类由热核产生的分式颜色噪声和随机Burgers方程解的定义。首先证明方程局部解的存在唯一性,再通过一致估计得到这类方程全局解的存在唯一性。

Abstract:
In this article, we are concerned with a class of stochastic Burgers equations driven by fractional-colorednoise which is fractional in time, with Hurst parameter h∈(1/2,1), and colored in space, with spatial covariance function. We introduce a fractional-colored noise when the spatial covariance function is heat kernel, and give the definition of the solution of the equation. We give the existence and uniqueness of local solution and use some uniformly estimates to show the existence and uniqueness of global solution.
