在Chern-Simons理论中,Chern-Simons形式的一般定义为:\[ CS(A) = \text{Tr}\left(A \wedge dA + \frac{2}{3}A \wedge A \wedge A\right) \]在我们的场景中,联络A的数学表达式为\(A = v \cdot \cos(\theta) d\phi\),而曲率F的数学表达式为\(F = -v \cdot \sin(\theta) d\theta \wed...

The evolution of $ilde {w} $ in a flat FRW universe is studied, and it is shown that the parameters of the theory admit solutions wherein it is possible to have an equation of state $p_\\\phi \\\approx -\\\epsilon_\\\phi $, so that it leads to an accelerating universe. We ...
As is well-known, three of the four fundamental interactions of nature — electromagnetism, weak and strong interactions—are accurately described as Yang-Mills (YM) theories in the Standard Model, o...
We investigate the Chern–Simons-like formulation of exotic general massive gravity models within the framework of third-way to three-dimensional gravity. We classify our construction into two main approaches: one using torsional cosmological Einstein and exotic massive gravity equations, and the other ...
