Improved existence for the characteristic initial value problem with the conformal Einstein field equations
David Hilditch, Juan A. Valiente Kroon, Peng Zhao
We adapt Luk's analysis of the characteristic initial value problem in General Relativity to the asymptotic characteristic problem for the conformal Einstein field equations to dem…
Revisiting the characteristic initial value problem for the vacuum Einstein field equations
David Hilditch, Juan A. Valiente Kroon, Peng Zhao
Using the Newman-Penrose formalism we study the characteristic initial value problem in vacuum General Relativity. We work in a gauge suggested by Stewart, and following the strate…
The Quasi-normal Modes of Charged Scalar Fields in Kerr-Newman black hole and Its Geometric Interpretation
Peng Zhao, Yu Tian, Xiaoning Wu +1
It is well-known that there is a geometric correspondence between high-frequency quasi-normal modes (QNMs) and null geodesics (spherical photon orbits). In this paper, we generaliz…
