After a fixed number of steps, the left tail has a Gaussian profile under minimal assumptions. Remarkably, a similar phenomenon occurs when we consider a positive random walk on the cone of positive-semidefinite matrices. After a fixed number of steps, the minimum eigenvalue is described by a Gaussian random matrix model.<br>\r\nThis talk introduces a new way to make this intuition rigorous. The methodology addresses an open problem in computational mathematics about sparse random embeddings. The presentation targets a general mathematical audience.<br>\r\nPreprint: <a href=\"https://arxiv.org/abs/2501.16578\" target=\"_blank\">https://arxiv.org/abs/2501.16578</a><br>\r\n<br>\r\n<strong>Please register on the following form : </strong>https://forms.gle/ppXwKo9HmTgFk3rc7", "image_description": "", "creation_date": "2026-04-01T11:03:30", "last_modification_date": "2026-04-01T11:03:45", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "BCH 2201", "url_place_and_room": "https://plan.epfl.ch/?room==BCH%202201", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "Prof. Joel A.
