非球对称标量场分布的坍缩

Collapse of non-spherically symmetric scalar field distributions

Koyel Ganguly, Narayan Banerjee

摘要:

本文研究了具有最小耦合标量场的精确非球模型的坍缩情形。研究了平面对称、环面对称、柱面对称和赝平面对称的标量场坍缩。结果表明,即使标量场具有与暗能量相对应的状态方程,它也可能具有坍缩模。

英文摘要:

In the present work the collapse scenario of some exact non-spherical models with a minimally coupled scalar field is studied. Scalar field collapse with planar as well as toroidal, cylindrical and pseudoplanar symmetries have been investigated. It is shown that the scalar field may have collapsing modes even if it has the equation of state corresponding to that of a dark energy.
