相互作用扩散方程组平衡点的存在性

Existence of equilibrium for Infinite System of Interacting Diffusions

Frantisek Zak

摘要:

我们开发并实现了新的概率策略来证明无界格点上相互作用扩散过程的长时间行为的基本结果。所使用的解决方案的概念是相当弱的,因为我们构造的过程作为一个解决适当的无限维鞅问题。然而,该技术允许我们考虑粒子的生成元是退化椭圆算子的情况。作为一个模型的例子,我们目前的情况下,运营商来自海森堡群。在最后一节中,我们提到了一些可以使用我们的方法处理的其他示例。

英文摘要:

We develop and implement new probabilistic strategy for proving basic results about long time behaviour for interacting diffusion processes on unbounded lattice. The concept of the solution used is rather weak as we construct the process as a solution to suitable infinite dimensional martingale problem. However the techniques allow us to consider cases where the generator of the particle is degenerate elliptic operator. As a model example we present situation, where the operator arises from Heisenberg group. In the last section we mention some further examples that can be handled using our methods.
