我们讨论了D=5最大超对称杨-米尔斯理论(MSYM)如何用于研究甚至定义六维的(2，0)理论。众所周知，(2，0)理论在圆上的紧化导致D=5MSYM。各种论证表明，这种关系是可以颠倒的，并且(2，0)理论的所有自由度在D=5MSYM中都已经存在。如果是这样的话，这个关系应该对D=5 SYM微扰理论产生影响。我们探讨它是否意味着所有的阶数有限，或者截断和规范耦合之间的一种不寻常的关系。约化到D=4的S对偶性可以提供对这些选项的非微扰约束或检验。
We discuss how D= 5 maximally supersymmetric Yang-Mills theory (MSYM) might be used to study or even to define the (2, 0) theory in six dimensions. It is known that the compactification of (2, 0) theory on a circle leads to D= 5 MSYM. A variety of arguments suggest that the relation can be reversed, and that all of the degrees of freedom of (2, 0) theory are already present in D= 5 MSYM. If so, this relation should have consequences for D= 5 SYM perturbation theory. We explore whether it might imply all orders finiteness, or else an unusual relation between the cutoff and the gauge coupling. S-duality of the reduction to D= 4 may provide nonperturbative constraints or tests of these options.
