$R=0$的动静解--标量张量理论

Dynamical and static solutions to $R=0$-scalar-tensor theory

Mustapha Azreg-Aïnou

摘要:

我们认为最有趣的宇宙学和相关的情况下标量张量理论(STT),并得出新的正常和幻影,动态和静态,解决方案。我们确定的Bianchi我Kasner指数,并表明,动力学解决方案是异宿轨道连接两个奇点。接近奇点时,可能会发生纯粹的横向膨胀(没有径向膨胀或坍缩)。

英文摘要:

We consider the most cosmologically interesting and relevant case of scalar-tensor theory (STT) and derive new normal and phantom, dynamical and static, solutions. We determine the Bianchi I Kasner exponents and show that the dynamical solutions are heteroclinic orbits connecting two singularities. Approaching the singularities, a purely transverse expansion (no radial expansion or collapse) may occur.
