具有乘性稳定Lévy噪声的heat equation

The heat equation with multiplicative stable Lévy noise

Carl Mueller, Leonid Mytnik, Aurel Stan

摘要:

研究了具有随机位势项的热方程。势是一个单侧稳定的噪声,具有正跳变,不依赖于时间。为了避免奇异性,我们定义的方程的建设类似的Skorokhod积分或威克产品。我们根据空间变量的维数和稳定噪声的参数p给出了存在性判据。对于p1,我们的论证是不同<1 and p>的.

英文摘要:

We study the heat equation with a random potential term. The potential is a one-sided stable noise, with positive jumps, which does not depend on time. To avoid singularities, we define the equation in terms of a construction similar to the Skorokhod integral or Wick product. We give a criterion for existence based on the dimension of the space variable, and the parameter p of the stable noise. Our arguments are different for p<1 and p>1.
