Mechanics of Apparent Horizon in Two Dimensional Dilaton Gravity

Understand

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.
