主要内容:
以前的时延都是基于标准宇宙学模型的，此文将其他宇宙学模型也考虑进来：four alternative models of dark energy (quintessence with constant and variable equation of state, Chaplygin gas and braneworld cosmology).
注意不是用其他的引力模型（导致不一样的洛仑兹违背），而是考虑不同的宇宙学模型（应该是导致不同的距离，从而有不同的时延吧。）

Abstract
Lorentz invariance violation (LIV) manifesting itself by energy-dependent modification of standard relativistic dispersion relation has recently attracted a considerable attention. Ellis et al previously investigated the energy-dependent time offsets in different energy bands on a sample of gamma ray bursts and, assuming standard cosmological model, they found a weak indication for redshift dependence of time delays suggestive of LIV. Going beyond the ΛCDM cosmology we extend this analysis considering also four alternative models of dark energy (quintessence with constant and variable equation of state, Chaplygin gas and braneworld cosmology). It turns out that the effect noted by Ellis et al is also present in those models and is the strongest for quintessence with a variable equation of state.
