• Displacement convexity of Boltzmann’s entropy characterizes positive energy in general relativity

    CMSA 20 Garden Street, Cambridge, MA, United States

    Speaker: Robert McCann (University of Toronto) Title: Displacement convexity of Boltzmann's entropy characterizes positive energy in general relativity Abstract: Einstein's theory of gravity is based on assuming that the fluxes of a energy and momentum in a physical system are proportional to a certain variant of the Ricci curvature tensor on a smooth 3+1 dimensional spacetime. The fact that […]
