Exact Solutions of the Einstein Equations for an Infinite Slab with Constant Energy Densityneous energy (mass) density is present. In the first solution, the pressure is isotropic, while in the second solution the tangential components of the pressure are equal to zero. In both cases, the pressure vanishes at the boundaries of the slab. Outside the slab, these solutions are matched with t

Introduction to the Wang–Yau Quasi-local Energyties. In the explanation of the definition of the Wang–Yau energy, we focus on its physical and variational feature and relate it to some previously known quasi-local quantities. In the end, we outline the ideas behind the proof of its positivity.
