On the min-max width of unit volume three-spheres
Lucas Ambrozio, Rafael Montezuma · Journal of Differential Geometry · 2024
How large can be the width of Riemannian three-spheres of the same volume in the same conformal class? If a maximum value is attained, how does a maximising metric look like? What happens as the conformal class changes? In this paper, we investigate these and other related questions, focusing on the context of Simon–Smith min‑max theory.
