带乘性噪声网络上的随机Allen-Cahn方程

On the stochastic Allen-Cahn equation on networks with multiplicative noise

Mihály Kovács, Eszter Sikolya

摘要:

本文考虑了有限网络上的随机Allen-Cahn方程组,该网络由有限图表示。在图中的每个边缘上,给出了乘性高斯噪声驱动的随机Allen-Cahn方程,其具有可能不同的势垒高度,并在顶点处补充了连续性条件和Kirchhoff型定律。利用巴拿赫空间中随机发展方程的半群方法,得到了图上连续函数空间中样本路径解的存在唯一性.我们还证明了更精确的时空正则性的解决方案。

英文摘要:

We consider a system of stochastic Allen-Cahn equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative Gaussian noise driven stochastic Allen-Cahn equation is given with possibly different potential barrier heights supplemented by a continuity condition and a Kirchhoff-type law in the vertices. Using the semigroup approach for stochastic evolution equations in Banach spaces we obtain existence and uniqueness of solutions with sample paths in the space of continuous functions on the graph. We also prove more precise space-time regularity of the solution.
