f(R)-引力的紫外性质

Ultraviolet properties of f(R)-Gravity

Alessandro Codello, Roberto Percacci, Christoph Rahmede

摘要:

本文讨论了f(R)-引力中非平凡不动点的存在性及其性质,其中f是一个六阶多项式.在这七个参数的理论中,不动点有三个紫外线吸引方向和四个紫外线排斥方向;这进一步支持了引力非微扰重整化的假设。

英文摘要:

We discuss the existence and properties of a nontrivial fixed point in f(R)-gravity, where f is a polynomial of order up to six. Within this seven-parameter class of theories, the fixed point has three ultraviolet-attractive and four ultraviolet-repulsive directions; this brings further support to the hypothesis that gravity is nonperturbatively renormalizabile.
