New Generalizations of Cosmography Inspired by the Pade Approximant
Ya-Nan Zhou, De-Zi Liu, Xiao-Bo Zou +1
The current accelerated expansion of the universe has been one of the most important fields in physics and astronomy since 1998. Many cosmological models have been proposed in the…
Hojman Symmetry in Theory
Hao Wei, Ya-Nan Zhou, Hong-Yu Li +1
Today, theory has been one of the popular modified gravity theories to explain the accelerated expansion of the universe without invoking dark energy. In this work, we consi…
Cosmological Applications of Pade Approximant
Hao Wei, Xiao-Peng Yan, Ya-Nan Zhou
As is well known, in mathematics, any function could be approximated by the Padé approximant. The Padé approximant is the best approximation of a function by a rational function of…
Cosmological Evolution of Einstein-Aether Models with Power-law-like Potential
Hao Wei, Xiao-Peng Yan, Ya-Nan Zhou
The so-called Einstein-Aether theory is General Relativity coupled (at second derivative order) to a dynamical unit time-like vector field (the aether). It is a Lorentz-violating t…
