标题： Super-renormalizable Gravity

摘要： 我们回顾了一类在量子层面上一致的高阶导数引力理论。 这类理论的特点是一个非多项式整体函数（形式因子），它避免了额外的自由度（包括鬼态）并改善了环状幅度的高能行为。 通过幂计数论证，证明该理论是超可重整化的，即只有单圈发散存在。 在经典层面上，黑洞和宇宙学解是无奇点的。 显示英文摘要

摘要： We review a class of higher derivative theories of gravity consistent at quantum level. This class is marked by a non-polynomal entire function (form factor), which averts extra degrees of freedom (including ghosts) and improves the high energy behaviour of the loop amplitudes. By power counting arguments, it is proved that the theory is super-renormalizable, i.e. only one-loop divergences survive. At classical level, black holes and cosmological solutions are singularity free.
