EQUIVALENCE OF PALM MEASURES FOR DETERMINANTAL POINT PROCESSES GOVERNED BY BERGMAN KERNELS
Résumé
For a determinantal point process induced by the reproducing kernel of the weighted Bergman space $A^2(U, \omega)$ over a domain $U \subset \mathbb{C}^d$, we establish the mutual absolute continuity of reduced Palm measures of any order provided that the domain $U$ contains a non-constant bounded holomorphic function. The result holds in all dimensions.
The argument uses the $H^\infty(U)$-module structure of $A^2(U, \omega)$. A corollary is the quasi-invariance of our determinantal point process under the natural action of the group of compactly supported diffeomorphisms of $U$.
