Web16 de jul. de 2024 · Formation of trapped surfaces from asymptotically flat Cauchy data (the work of Li and Yu ) Full size image. Fig. 5. Construction of dynamical black holes (the work of Dafermos–Hozegel–Rodnianski ) Full size image. Nevertheless, we may still have some indirect way to exhibit examples of collapsing spacetimes. WebTherefore, any trapped surface formation result necessarily requires the data to be “large” in a certain sense. Our theorem below in particular allows the data for the metric to be large only in H3 2 (as opposed to H1 in Theorem 1.2), which is a scaling-critical norm5 for the Einstein equations:
Web17 de set. de 2024 · Trapped nanobubbles are gas domains trapped at nanopits on the solid-liquid interface. This is different from surface nanobubbles that usually form at the smooth surface. Herein, both trapped nanobubbles and surface nanobubbles formed on the nanopitted polystyrene film were studied by a spontaneous … Web12 de abr. de 2024 · The neutral (NN)–B–B–B–(N2) complex has been trapped in low-temperature dinitrogen matrix and identified by isotopic substitution and theoretical frequency calculations. The linear B–B–B skeleton is stabilized by two inequivalent N2, namely, one end-on and other side-on N2. The structure of linear B–B–B skeleton …
