Not Only Scalar Curvature

Fedor Manin: How hard is the theorem of Stoltz?
(10:30 am NYC, 16:30 Paris)
Stoltz, building on work of Gromov–Lawson and Atiyah–Singer–Lichnerowicz–Hitchen, discovered exactly which simply connected spin manifolds have metrics of positive scalar curvature. Now say someone gives you a metric on a manifold which admits a metric of positive scalar curvature. How much more complicated do you have to make this metric so that it actually has positive scalar curvature? How hard is it to find a deformation between these two metrics? I will discuss joint work with Shmuel Weinberger, Zhizhang Xie and Guoliang Yu which gives some answers to these questions.

Previous talks


Seminar Info

Each session will consist of one or two lectures on a recent advance in geometry. Not all the talks will concern scalar curvature but perhaps many will. Each talk will be followed by a discussion both in person and online. Everyone is welcome to join the session live (zoom) or watch the recorded videos of the talks later.


Zoom starts at 10:30 am NYC time:
