Extension of photon surfaces and their area: Static and stationary spacetimes
Hirotaka Yoshino, Keisuke Izumi, Tetsuya Shiromizu +1
We propose a new concept, the transversely trapping surface (TTS), as an extension of the static photon surface characterizing the strong gravity region of a static/stationary spac…

Area bound for a surface in a strong gravity region
Tetsuya Shiromizu, Yoshimune Tomikawa, Keisuke Izumi +1
For asymptotically flat spacetimes, using the inverse mean curvature flow, we show that any compact -surface, , whose mean curvature and its derivative for outward directio…
