摘要
Hopfions are a family of `solitonary’ solutions of the N-spin field with a non-trivial topological structure related to Hopf fibration. During the talk, I will focus on electromagnetic and linearized gravity cases. Conserved quantities, in particular energy and topological charges, will be discussed. Recent attempts at generalization of hopfions will also be presented.
