In the Einstein–Cartan gravitational theory with the chameleon field, while changing its mass independently of the density of its environment, we analyze the Friedmann–Einstein equations for the Universe’s evolution with the expansion parameter a being dependent on time only. We analyze the problem of an identification of the chameleon field with quintessence, i.e., a canonical scalar field responsible for dark energy dynamics, and for the acceleration of the Universe’s expansion. We show that since the cosmological constant related to the relic dark energy density is induced by torsion (Astrophys. J.2016, 829, 47), the chameleon field may, in principle, possess some properties of quintessence, such as an influence on the dark energy dynamics and the acceleration of the Universe’s expansion, even in the late-time acceleration, but it cannot be identified with quintessence to the full extent in the classical Einstein–Cartan gravitational theory.

变色龙领域能否用精髓来识别？

在具有变色龙场的爱因斯坦–卡丹引力理论中，在不依赖其环境密度的情况下改变其质量的同时，我们分析了宇宙演化的弗里德曼–爱因斯坦方程，其膨胀参数a仅取决于时间。我们分析了具有典型特征的变色龙场的识别问题，即典型的标量场负责暗能量动力学以及宇宙膨胀的加速。我们发现，由于相关的遗物暗能量密度宇宙常数被扭曲（诱导Astrophys。J. 2016，829（47），变色龙场原则上可以具有一些典型的性质，例如对暗能量动力学的影响和宇宙膨胀的加速，即使是在后期的加速中，但也不能用典型来识别在经典的爱因斯坦-卡丹引力理论中得到了充分的发挥。
