Conditional measures of determinantal point processes

An explicit description is given for conditional measures of determinantal point processes corresponding to integrable kernels in one dimension, including those corresponding to de Branges spaces (joint work with Tomoyuki Shirai), as well as to kernels of orthogonal projection onto generalized Fock spaces (joint work with Yanqi Qiu). The main result is that the conditional measure of our process in a bounded domain with respect to the fixed configuration in the exterior is an orthogonal polynomial ensemble with explicitly found weight. For Bergman spaces in bounded domains, in joint work with Shilei Fan and Yanqi Qiu, it is shown that the determinantal point process is equivalent to its reduced Palm measures.
