论文摘要
令$ f $为整个功能。逃脱的集合$ i（f）$由$ f $的迭代中倾向于无限的积分组成。我们表明$ i（f）$不是$σ$ - compact，从2009年开始解决了里彭的问题。
Let $f$ be a transcendental entire function. The escaping set $I(f)$ consists of those points that tend to infinity under iteration of $f$. We show that $I(f)$ is not $σ$-compact, resolving a question of Rippon from 2009.
