Seminarium KMMF "Teoria Dwoistości"

The limit of vanishing G (Newton's constant of universal gravitation) of the maximal analytically extended Kerr--Newman electrovacuum spacetime gives a locally flat spacetime with a topologically non-trivial electromagnetic field. The properties of the system in the context of classical and recent points of view on the issue will be discussed. New results on the interaction of two Magic fields will also be presented.
