Multiplicity of Finsler geodesics and electromagnetic trajectories via localized deformations
Erasmo Caponio, Anna Valeria Germinario, Antonio Masiello
Given a Finsler manifold and suitable nested regions , with connected and non-contractible, as in the model case of concentric b…
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 the formulations of the Fermat principle in general relativity and beyond
Erasmo Caponio, Miguel Angel Javaloyes
This paper presents a survey of the Fermat principle within the framework of general relativity, tracing its evolution from classical optics to its modern variational formulation i…
A unified framework for photon and massive particle hypersurfaces in stationary spacetimes
Erasmo Caponio, Anna Valeria Germinario, Anna valeria Germinario +1
Massive particle surfaces (MPS), introduced by Kobialko, Bogush and Gal'tsov, are timelike hypersurfaces confining the trajectories of charged massive particles with fixed Killing…
Static spacetimes with a Finsler angular sector
Erasmo Caponio
We consider static spacetimes in spherical coordinates whose angular sector is described by a Finsler metric rather than the standard round metric on . Our first contribution…
On a nonlinear Schrödinger-Bopp-Podolsky system in the zero mass case: functional framework and existence
Erasmo Caponio, Pietro d'Avenia, Alessio Pomponio +2
In this paper, we consider in the following zero mass Schrödinger-Bopp-Podolsky system \[ \begin{cases} -Δu +q^2ϕu=|u|^{p-2}u\\ -Δϕ+a^2Δ^2ϕ=4πu^2 \end{cases} \] wher…
