In [Kab15], the author established the conjecture stated by Pemantle and Rivin in [PR13] that the empirical measure $\\nu_n$ associated with the critical points of $P_n$ converges weakly in probability to the base measure $\\mu$. In this note, we establish that the convergence in fact holds in the almost sure sense. Our result positively answers a question raised by Z. Kabluchko and formalized as a conjecture in the recent paper [MV22].", "revisions": [ { "version": "v1", "updated": "2023-01-17T15:52:28.000Z" } ], "analyses": { "subjects": [ "30C15", "60G57", "60B10" ], "keywords": [ "critical points", "sure behavior", "identically distributed complex random variables", "conjecture", "common distribution" ], "note": { "typesetting": "TeX", "pages": 16, "language": "en", "license": "arXiv", "status": "editable" } } }
