ALE Metrics and Nodal Curves - Kronheimer's Construction and Alternative Approaches

Explore Kronheimer's construction of asymptotically locally Euclidean (ALE) metrics on Kleinian singularity resolutions through an alternative approach presented by Nigel Hitchin from the University of Oxford. Delve into the algebraic geometry of twistor spaces and circle actions on resolutions, examining their connections to ALE metrics. Investigate the role of nodal curves in linear systems on rational surfaces and their relationship to the differential geometry of three-dimensional ALE space quotients. This hour-long lecture offers a deep dive into advanced topics in algebraic geometry and differential geometry, providing insights into alternative methods for understanding ALE metrics and their connections to various mathematical structures.
