a Homological Invariant in the Relativistic Rays Optics
Abstract
The optics of light rays in a general-relativistic medium can be described using a Hamiltonian formalism. In this note we discuss some mathematical issues related to the notion of Maslov index for a solution of a Hamiltonian problem, aiming at applications to the study of the gravitational lensing effect.
