On the local well-posedness of Lovelock and Horndeski theories
(American Physical SocietyPhysical Review D - Particles, Fields, Gravitation and Cosmologyhttp://dx.doi.org/10.1103/PhysRevD.96.044019, 2017-08-15)
We investigate local well-posedness of the initial value problem for Lovelock and Horndeski theories of gravity. A necessary condition for local well-posedness is strong hyperbolicity of the equations of motion. Even weak ...
