Mechanics of Apparent Horizon in Two Dimensional Dilaton Gravity (1609.08306v1)
Published 27 Sep 2016 in gr-qc
Abstract: In this article, we give a definition of apparent horizon in a two dimensional general dilaton gravity theory. With this definition, we construct the mechanics of the apparent horizon by introducing a quasi-local energy of the theory. Our discussion generalizes the apparent horizons mechanics in general spherically symmetric spactimes in four or higher dimensions to the two dimensional dilaton gravity case.
