We prove several theorems concerning the connection between the local CR embeddability of 3-dimensional CR manifolds, and the existence of algebraically special Maxwell and gravitational fields. We ...

The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...

Proposed 15 years ago, the bounded L2 curvature conjecture has finally been proven by a group of researchers. It provides a potentially minimal framework in which it is possible to solve the Einstein ...
