Autumn 2025
The Seminar runs on Tuesdays at STRAND BLDG S5.20. This term, some talks will run from 15:00 to 16:00, and others will be in two parts – an introductory talk from 15:00 to 15:40 and a research talk from 15:45 to 16:30.
14 October, 15:00-16:00, STRAND BLDG S5.20
Speaker: Luca Tasin (Univeristy of Milan)
Title: Sasaki–Einstein metrics on spheres
Abstract: The differential geometry of spheres has long been a source of central problems in mathematics, and Sasaki–Einstein metrics—odd-dimensional analogues of Kähler–Einstein metrics—offer a particularly rich perspective, with significance both in geometry and in theoretical physics. In joint work with Yuchen Liu and Taro Sano, we construct infinitely many Sasaki–Einstein metrics on odd-dimensional spheres that bound parallelizable manifolds, thereby confirming conjectures of Boyer–Galicki–Kollár and Collins–Székelyhidi. Our approach is based on establishing the K-stability of certain Fano weighted hypersurfaces.
