Title: A compactness theorem for Einstein metrics on the four-sphere
Speaker: Harish Seshadri (IISc Mathematics)
Date: 25 February 2019
Time: 4 pm
Venue: LH-1, Mathematics Department

It is open question if the standard round metric on $S^4$ is the unique positive Einstein metric, up to isometry and scaling. In this talk, I will discuss a compactness theorem which rules out nonstandard unit-volume Einstein metrics whose scalar curvatures lie within a certain range.
