#### From Yang-Mills and Maxwell in de Sitter space electromagnetic knots

Regular Seminar Olaf Lechtenfeld (Hannover)

 at: 15:00 City U.room AG21 abstract: I will review analytic SU(2) Yang-Mills solutions with finite action on de Sitter space from a new perspective. As a byproduct, all abelian solutions are classified and related with rational electromagnetic knots. In the Yang-Mills case, the gravitational backreaction is easily taken in to account as well.
