The Kähler-Einstein metric on the third Del Pezzo surface
Timothy Buttsworth, William Hadden, Elli Heyes +2
The compact four-dimensional manifold is known to admit a toric Kähler-Einstein metric , but the metric is not known in c…

An isoperimetric problem for Fourier zeros of centrally symmetric convex bodies
Javier Gómez-Serrano, Michael Levitin, Daniel Platt +1
Given a centrally symmetric convex body, consider the zero set of the Fourier transform of its characteristic function. We study how large the distance from this set to the origin…

Non-uniqueness and symmetries for the Nirenberg problem using computer assistance
Daniel Platt
We apply verified numerics to the Nirenberg problem, proving that a genuine solution exists near two given computer-generated approximate solutions. This proves existence of a solu…
