Electromagnetic and Gravitational Hopfion-like solutions in de Sitter spacetime
Hopfions are a family of `solitonic’ field solutions that have a non-trivial topological structure associated with the Hopf fibration. I will present a generalisation of such solutions, based on conformal transformations, to de Sitter spacetime. Topological charges will be discussed.
