Geometry and Topology Seminar: Ricci Solitons and Quasi Einstein metrics on toric surfaces

Presented by Stuart Hall , Newcastle

19 January 2017 13:00 in CM221

Ricci solitons and quasi-Einstein metrics are two natural and related generalisations of the Einstein condition. I will report on some work with Thomas Murphy and Wafaa Batat where we investigate the geometry of these metrics on some special 4-dimensional manifolds (the toric surfaces of the title). I'll also detail some numerical work with Thomas Murphy giving explicit approximations to such metrics.
