对于在有效作用下具有任意一组高导数项的与任意物质场耦合的一般三维（超）引力理论，给出了将该理论一致截断为引力扇区仅包含爱因斯坦-希尔伯特项、宇宙常数项和陈-西蒙斯项的纯（超）引力理论的算法。我们还概述了寻找截断理论参数的过程。作为一个例子，我们考虑了带曲率平方项的5维最小超引力在S2上的降维，得到了不带曲率平方项的截断理论。这种截断理论正确地再现了边界CFT的中心电荷。
For a general three dimensional theory of (super-)gravity coupled to arbitrary matter fields with arbitrary set of higher derivative terms in the effective action, we give an algorithm for consistently truncating the theory to a theory of pure (super-)gravity with the gravitational sector containing only Einstein-Hilbert, cosmological constant and Chern-Simons terms. We also outline the procedure for finding the parameters of the truncated theory. As an example we consider dimensional reduction on S2 of the 5-dimensional minimal supergravity with curvature squared terms and obtain the truncated theory without any curvature squared terms. This truncated theory reproduces correctly the exact central charge of the boundary CFT.
