摘要：This minicourse focuses on random point processes and consists of two parts. In the first part, we will consider the limiting behavior of (multivariate) linear statistics of determinantal point processes via a graphical representation for their cumulants. We will establish a Wiener chaos decomposition result using an operator formulation and a cumulant cancellation scheme, generalizing classical results on U-statistics based on i.i.d. random variables. In the second part, we will discuss small and large gaps of random point processes. The problem essentially boils down to three ingredients: local scaling of gaps, independence for far-away gaps, and a non-clustering property. We will present a few examples, including zeros of smooth stationary Gaussian processes, zeros of Gaussian holomorphic sections, and eigenvalues of random matrices.
