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.

Complex methods in General Relativity
AbstractFollowing a brief introduction to complex manifolds, the course will explore connections between general relativity, the Einstein equation,and complex geometry. Among the topics I would like to cover are manifestations of Kähler and Hermitian geometry in general relativity, as well as twistor theory and its applications in general relativity and field theory. The course will be accessib...
