布朗自输运算子的显式构造

Explicit Construction of the Brownian Self-Transport Operator

D. S. Grebenkov

摘要:

利用对具有紧支集的一维正则曲面(曲线)发展的特征函数技术,得到了一类正方形格上有限膜的命中概率分布.然后将其推广到超立方格上的多维有限膜。基于这些分布,我们明确地构造了布朗自输运算子,它支配拉普拉斯转移。为了验证命中概率分布的准确性,对一些特殊的膜进行了数值分析。

英文摘要:

Applying the technique of characteristic functions developped for one-dimensional regular surfaces (curves) with compact support, we obtain the distribution of hitting probabilities for a wide class of finite membranes on square lattice. Then we generalize it to multi-dimensional finite membranes on hypercubic lattice. Basing on these distributions, we explicitly construct the Brownian self-transport operator which governs the Laplacian transfer. In order to verify the accuracy of the distribution of hitting probabilities, numerical analysis is carried out for some particular membranes.
