Gauss-Bonnet Gravity and Spacetime Singularities
Tariq Allaithy, Adel Awad, Mohamed Hany Radwan +1
We investigate the effect of higher-order curvature terms, specifically Gauss-Bonnet terms, on spacetime singularities in five dimensions. For FLRW cosmologies, we demonstrate that…

Generalized Replica Manifolds I: Surgery and Averaging
Mohamed Hany Radwan
We develop a simple framework for implementing a type of path integral "surgery" via correlated averaging over codimension-one defects/extended operators. This technique is used to…

Operators in the Internal Space and Locality
Hardik Bohra, Sumit R. Das, Gautam Mandal +3
Realizations of the holographic correspondence in String/M theory typically involve spacetimes of the form where is some internal space which geometrizes an inte…
