Antoine Song

Antoine Song (born 18 July 1992 in Paris) is a French mathematician whose research concerns differential geometry. In 2018, he proved Yau's conjecture. He is a Clay Research Fellow (2019–2024). He obtained his Ph.D. from Princeton University in 2019 under the supervision of Fernando Codá Marques. He is an assistant professor of mathematics at Caltech. He is a Sloan Fellow. In 2023, together with Conghan Dong, he proved a conjecture from 2001 by Huisken and Ilmanen on the mathematics of general relativity, about the curvature in spaces with very little mass.

Existence of minimal surfaces
It is known that any closed surface possesses infinitely many closed geodesics. The first problem in the minimal submanifolds section of Yau's list asks whether any closed three-manifold has infinitely many closed smooth immersed minimal surfaces. At the time it was known from Almgren–Pitts min-max theory the existence of at least one minimal surface. Kei Irie, Fernando Codá Marques, and André Neves solved this problem in the generic case and later Antoine Song claimed it in full generality.
