Loosely trapped surface for slowly rotating black hole
Keisuke Izumi, Tetsuya Shiromizu, Daisuke Yoshida +2
We construct the marginal loosely trapped surface (marginal LTS) for the Kerr spacetime with a small Kerr parameter perturbatively, where the LTS condition is saturated. An LTS is…

Attractive gravity probe surface in Einstein-Maxwell system
Kangjae Lee, Keisuke Izumi, Tetsuya Shiromizu +2
We derive areal inequalities for five types of attractive gravity probe surfaces, which were proposed by us in order to characterize the strength of gravity in different ways inclu…
