Thesis Title New avenues for Einstein's gravity: From Penrose's twistors to Hitchin three-forms
Thesis Abstract General Relativity can be reformulated as a theory of connections rather than metrics. In this formulation, the so-called gravitational instanton sector of GR admits an immediate lift to Penrose's twistor space. The aim of this project is to explore the relation between the gauge-theoretic and twistor descriptions of gravity in more depth, as well as to explore the possibility of lifting to twistor space the full General Relativity, and not just its self-dual sector.
