Abstract
Let be a translation-invariant point process on the complex plane , and let be a bounded open set. We ask the following: What does the point configuration obtained by taking the points of outside tell us about the point configuration of inside ? We show that, for the Ginibre ensemble, determines the number of points in . For the translation-invariant zero process of a planar Gaussian analytic function, we show that determines the number as well as the center of mass of the points in . Further, in both models we prove that the outside says “nothing more” about the inside, in the sense that the conditional distribution of the inside points, given the outside, is mutually absolutely continuous with respect to the Lebesgue measure on its supporting submanifold.
