Electric-magnetic duality in gravity and higher-spin fields

A Danehkar - Frontiers in Physics, 2019 - frontiersin.org
Over the past two decades, electric-magnetic duality has made significant progress in
linearized gravity and higher spin gauge fields in arbitrary dimensions. By analogy with …

Excising Curvature Singularities from General Relativity

A Simpson - arXiv preprint arXiv:2304.07383, 2023 - arxiv.org
