论文摘要
众所周知，在霍德斯基理论中，完全稳定的解决方案的构建受到所谓的无关定理的强烈限制。以前，已经使用了各种技术来避免定理的条件。在本文中，一种新的构建稳定解决方案的方式显示在一般的Horndeski理论中。我们考虑了较早研究的统一量规的情况。在此基础上，我们构建了一种空间平坦，稳定的弹跳和创世纪宇宙解决方案，该解决方案是通过与非规定标量场的一般相对性描述的。
It is known that the construction of a completely stable solution in Horndeski theory is restricted very strongly by the so-called no-go theorem. Previously, various techniques have been used to avoid the conditions of the theorem. In this paper a new way of constructing stable solutions are shown in the general Horndeski theory. We considered the situation in which the unitary gauge studied earlier turns out to be singular. On this basis we construct a spatially flat, stable bouncing and genesis Universe solutions which are described by General Relativity with non-conventional scalar field.
