The Robinson-Trautman (RT) spacetime is the simplest solution of General
Relativity (GR) describing a compact source surrounded by gravitational
waves. As an initial value problem, the RT spacetime evolution is a
well-posed mathematical problem. The pertinent dynamical equations are
equivalent to the so-called Calabi flow, and regular initial data evolve
Our collaborator Kunihito Uzawa from Japan together with Zakaria Belkhadria, a Ph.D. student from U. Cagliari, Italy, are our guests this week. Zakaria is visiting us within a short term scientific mission of the COST action CA18108.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
