利用AdS7× S4上的超引力，计算了描述N个重合M5膜的（2，0）理论的体单圈共形反常.当这被添加到树水平的结果，和一个额外的子领导阶的贡献计算Tseytlin，它给出了一个表达式的异常，正确地插入之间的大N理论和自由（2，0）张量理论对应于N=1。因此，我们可以认为，我们已经确定了确切的N依赖的异常，这可能有一个简单的保护形式有效远离大N限制。
Using Supergravity on AdS7×S4we calculate the bulk one-loop contribution to the conformal anomaly of the (2,0) theory describing N coincident M5 branes. When this is added to the tree-level result, and an additional subleading order contribution calculated by Tseytlin, it gives an expression for the anomaly that interpolates correctly between the large N theory and the free (2,0) tensor theory corresponding to N=1. Thus we can argue that we have identified the exact N-dependence of the anomaly, which may have a simple protected form valid away from the large N limit.
