We obtain the asymptotic behavior of the variance, the exact value of the asymptotic constant, and non-asymptotic upper and lower bounds for the variance on a compact set {\\Omega} contained in C^+. As a special case one recovers the DPP related to the weighted Bergman kernel. When {\\psi} is chosen within a finite family whose Fourier transform are Laguerre functions, we obtain the DPP associated to hyperbolic Landau levels, the eigenspaces of the finite spectrum of the Maass Laplacian with a magnetic field.", "revisions": [ { "version": "v1", "updated": "2022-10-15T07:05:26.000Z" } ], "analyses": { "keywords": [ "determinantal point processes", "affine ensemble", "hyperbolic landau levels", "asymptotic behavior", "exact value" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
