随机粘性Cahn-Hilliard方程的适定性、正则性和粘性极限消失

The stochastic viscous Cahn-Hilliard equation: well-posedness, regularity and vanishing viscosity limit

Luca Scarpa

摘要:

证明了具有齐次Neumann边界条件和Wiener乘性噪声的随机粘性Cahn-Hilliard方程的适定性.允许双阱势在无穷远处有任何增长(特别是,也是超多项式),只要它在任何地方都定义在实数线上。一个消失的粘性参数进行和收敛的纯Cahn-Hilliard方程的解决方案。一些精细的正则性结果也推导出粘性和非粘性的情况下。

英文摘要:

Well-posedness is proved for the stochastic viscous Cahn-Hilliard equation with homogeneous Neumann boundary conditions and Wiener multiplicative noise. The double-well potential is allowed to have any growth at infinity (in particular, also super-polynomial) provided that it is everywhere defined on the real line. A vanishing viscosity argument is carried out and the convergence of the solutions to the ones of the pure Cahn-Hilliard equation is shown. Some refined regularity results are also deduced for both the viscous and the non-viscous case.
