标题： Spinorial quasilocal mass for spacetimes with negative cosmological constant

摘要： 一种新的准局部质量概念被定义为四维时空中有负宇宙常数的通用、紧致、二维、类空曲面。 该定义是旋量形式的，基于Penrose和Dougan & Mason对于宇宙常数为零的情况的工作。 此外，这种质量是非负的，在球对称情况下等于Misner-Sharp质量，对于AdS中的每个通用曲面都等于零，在关于AdS的引力线性化情况下具有适当的形式，并且在渐近AdS时空中的大球面上具有适当的极限。 显示英文摘要

摘要： A new notion of quasilocal mass is defined for generic, compact, two dimensional, spacelike surfaces in four dimensional spacetimes with negative cosmological constant. The definition is spinorial and based on work for vanishing cosmological constant by Penrose and Dougan & Mason. Furthermore, this mass is non-negative, equal to the Misner-Sharp mass in spherical symmetry, equal to zero for every generic surface in AdS, has an appropriate form for gravity linearised about AdS and has an appropriate limit for large spheres in asymptotically AdS spacetimes.
