Abstract

Hopfions are a family of `solitonary solutions of the N-spin field with a non-trivial topologicalstructure related to Hopf fibration. During the talk, l wil focus on electromagnetic and linearizedgravity cases. Conserved guantities, in particular energy and topoloaical charges, will be discussedRecent attempts at generalization of hopfions will also be presented.
