Torsion Cosmology of Poincaré gauge theory and the constraints of its parameters via SNeIa data
Xi-Chen Ao, Xin-Zhou Li
Poincarè gauge theory (PGT) is an alternative gravity theory, which attempts to bring the gravity into the gauge-theoretic frame, where the Lagrangian is quadratic in torsion and c…
de Sitter Gauge Theory of Gravity: An Alternative Torsion Cosmology
Xi-Chen Ao, Xin-Zhou Li
A new cosmological model based on the de Sitter gauge theory (dSGT) is studied in this paper. By some transformations, we find, in the dust universe, the cosmological equations of…
Cosmological Dynamics of de Sitter Gravity
Xi-chen Ao, Xin-zhou Li, Ping Xi
A new cosmological model based on the de Sitter gravity is investigated by dynamical analysis and numerical discussions. Via some transformations, the evolution equations of this m…
Analytical approach of late-time evolution in a torsion cosmology
Xi-chen Ao, Xin-zhou Li, Ping Xi
In this letter, we study the late-time evolution of a torsion cosmology only with the spin- mode. We find three kinds of analytical solutions with a constant affine scalar cur…
A simple derivation of level spacing of quasinormal frequencies for a black hole with a deficit solid angle and quintessence-like matter
Ping Xi, Xi-chen Ao, Xin-zhou Li
In this paper, we investigate analytically the level space of the imaginary part of quasinormal frequencies for a black hole with a deficit solid angle and quintessence-like matter…
