The Phase Space for the Einstein-Yang-Mills Equations and the First Law of Black Hole Thermodynamics
The Einstein-Yang-Mills constraint equations form a system of “almost elliptic” nonlinear PDE, describing the gravitational field coupled to gauge fields. In this talk we provide a Hilbert manifold structure for the space of solutions to this system on an asymptotically flat manifold; this ensures the validity of first-order perturbation theory for the system. Using this Hilbert manifold structure, we demonstrate that the first law of black hole mechanics gives a condition for a solution to be stationary.
