Seminarium Teorii Względności i Grawitacji

It turns out that the Kerr-NUT metric is the most general electrovacuum solution of axially symmetric spacetime admitting separable of variables for the Hamilton-Jacobi and the Klein-Gordon equations. The metric admits an interesting invariance when mass and NUT parameters and radial and angle coordinates are interchanged. Note that mass is gravoelectric charge while NUT parameter is gravomagnetic charge, and the duality transformation is therefore between gravoelectric and gravomagnetic charges along with the corresponding coordinates, radial and angle. In particular, Kerr and massless rotating NUT solutions are dual to each-other.

The seminar will also be broadcasted via Zoom, for the link contact Maciej Ossowski.
