Complexity factor for a static self-gravitating sphere in Rastall-Rainbow gravity
Zhou-Li Ye, Yu Wang, Rui-Xin Yang +1
We generalized Herrera's definition of complexity factor for static spherically symmetric fluid distributions to Rastall-Rainbow theory of gravity. For this purpose, an energy-depe…

Tilted spacetime positive mass theorem with arbitrary ends
Daoqiang Liu
In this paper, we prove the spacetime positive mass theorem for asymptotically flat spin initial data sets with arbitrary ends and a non-compact boundary. Moreover, we demonstrate…
