Domain wall space-times with a cosmological constant
Chih-Hung Wang, Hing-Tong Cho, Yu-Huei Wu
We solve vacuum Einstein's field equations with the cosmological constant in space-times admitting 3-parameter group of isometries with 2-dimensional space-like orbits. The general…
Classical and Quantum Mechanics with Poincare-Snyder Relativity
Otto C. W. Kong, Hung-Yi Lee
The Poincaré-Snyder relativity was introduced in an earlier paper of ours as an extended form of Einstein relativity obtained by appropriate limiting setting of the full Quantum Re…
Poincare gauge theory of gravity: Friedman cosmology with even and odd parity modes. Analytic part
Peter Baekler, Friedrich W. Hehl, James M. Nester
We propose a cosmological model in the framework of the Poincaré gauge theory of gravity (PG). The gravitational Lagrangian is quadratic in curvature and torsion. In our specific m…
Gravitational radiation and angular momentum flux from a slow rotating dynamical black hole
Yu-Huei Wu, Chih-Hung Wang
A four-dimensional asymptotic expansion scheme is used to study the next order effects of the nonlinearity near a spinning dynamical black hole. The angular momentum flux and energ…
Algebraic Rainich conditions for the tensor V
Lau Loi So
Algebraic conditions on the Ricci tensor in the Rainich-Misner-Wheeler unified field theory are known as the Rainich conditions. Penrose and more recently Bergqvist and Lankinen ma…
A momentum-space representation of Feynman propagator in Riemann-Cartan spacetime
Yu-Huei Wu, Chih-Hung Wang
We first construct generalized Riemann-normal coordinates by using autoparallels, instead of geodesics, in an arbitrary Riemann-Cartan spacetime. With the aid of generalized Rieman…
