最近导出的一个关于弹跳宇宙论的体积波动的不等式,适用于弹跳后很长一段时间处于半经典状态的不等式,它对弹跳前的波动没有足够强的限制,不能得出弹跳前的状态是半经典的结论,除非在非常弱的意义上。
A recently derived inequality on volume fluctuations of a bouncing cosmology, valid for states which are semiclassical long after the bounce, does not restrict pre-bounce fluctuations sufficiently strongly to conclude that the pre-bounce state was semiclassical except in a very weak sense.
