论文摘要
我们研究了2d $ f（r）$重力的规范结构。当出现什么样的情况下，证明了它与Jackiw-Teitelboim重力的等效性。然后，由于广告$ _2 $/cft $ _1 $对应关系，这种$ f（r）$重力等效于sachdev-ye-kitaev型号。还研究了$ f（r）$重力的单数$ d \至2 $限制。结果表明，在这样的限制中，未实现$ _2 $/cft $ _1 $的通信。
We studied the canonical structure of 2D $F(R)$ gravity. Its equivalence with Jackiw-Teitelboim gravity is demonstrated when no matter presents. Then, due to AdS$_2$/CFT$_1$ correspondence, such $F(R)$ gravity is equivalent to the Sachdev-Ye--Kitaev models. The singular $D\to 2$ limit of $F(R)$ gravity is also studied. It is shown that in such a limit AdS$_2$/CFT$_1$ correspondence is not realized.
