Sharp Tangential NEC Minimization and Israel Surface Layers in Schwarzschild Mass Interpolations

Changsun Choi, Ryan E. Grady

We study static, spherically symmetric metrics in Schwarzschild gauge whose mass function increases smoothly from $M_{1}$ to $M_{2} > M_{1}$ across an annulus $[R_{1}, R_{2}]$ outside the large…

Functoriality of the KSGNS Construction for Intertwiners of Strict Positive $C^{*}$ -Correspondences

Lucus Brady, Ryan Grady

We prove that the KSGNS construction can be viewed as an endofunctor on a category whose objects are positive $C^{*}$ -correspondences from a fixed $C^{*}$ -algebra and morphisms are giv…
