Existence of the longest arcs for left-invariant three-dimensional contact sub-Lorentzian structures

A. V. Podobryaev

The paper studies the existence of longest arcs—optimal curves—for left-invariant three-dimensional contact sub-Lorentzian structures, providing sufficient conditions for such arcs…
