摘要:

利用${\cal N}=2$规范超引力极值解的吸引子机制,构造了一个$c$ -函数,该函数在对应于反德西特几何的紫外和红外共形不动点处的理论中心荷之间进行插值.我们得到的$c$ -函数是纯用体量表示的,并且在RG流下的稳定共形不动点处连接两个不同维的CFTs。

英文摘要:

Using the attractor mechanism for extremal solutions in ${\cal N}=2$ gauged supergravity, we construct a $c$-function that interpolates between the central charges of theories at ultraviolet and infrared conformal fixed points corresponding to anti-de Sitter geometries. The $c$-function we obtain is couched purely in terms of bulk quantities and connects two different dimensional CFTs at the stable conformal fixed points under the RG flow.
