Closed and broken electromagnetic orbits in Kerr--Newman spacetime
Erasmo Caponio, Giulio Sanzeni, Stefan Suhr
We study future-pointing timelike solutions of the Lorentz force equation in the sub-extremal Kerr--Newman spacetime, with special attention to the time-machine region $\mathfrak T…

On homotopy properties of solutions of some differential inclusions in the -topology
Erasmo Caponio, Antonio Masiello, Stefan Suhr
We consider a differential inclusion on a manifold, defined by a field of open half-spaces whose boundary in each tangent space is the kernel of a one-form. We make the assumption…
