行列式过程与随机控制

Determinantal Processes and Stochastic Domination

Raghavendra Tripathi

摘要:

证明了有限秩投影核的行列式过程的随机控制性。这一结果首先由Lyons在离散条件下证明。我们避免机器的拟阵,以获得一个证明,工程在一般情况下。我们证明了另一个结果的随机控制的两个决定性的过程中的内核表示相对于不同的措施。将这个结果与Lyons的随机控制定理相结合,我们得到了关于$\mathbb{Z}^2$上有向最后一段渗流的最后一段时间的随机控制的一个结果.几何权重

英文摘要:

We prove the stochastic domination for determinantal processes associated with finite rank projection kernels. The result was first proved by Lyons in discrete setting. We avoid the machinery of matroids in order to obtain a proof that works in a general setting. We prove another result on the stochastic domination of two determinantal processes where the kernels are represented with respect to different measures. Combining this result with Lyons' theorem on the Stochastic domination we obtain a result on the stochastic domination for the last passage time in a directed last passage percolation on $\mathbb{Z}^2$ with i.i.d. geometric weights.
