We prove that theories that arise by taking free hypermultiplets and gauging a subgroup of , the non-R global symmetry of the free theory, have a remaining global symmetry, which is a direct sum of unitary, symplectic, and special orthogonal factors. This implies that theories that have but not global symmetries, such as Gaiotto's theories, are not likely to arise as IR fixed points of RG flows from weakly coupled gauge theories.
我们证明，通过取自由超多重态并对自由理论的非R整体对称性 的一个子群进行规范而产生的理论，具有剩余的整体对称性，它是酉、辛和特殊正交因子的直和。这意味着具有 但不具有 整体对称性的理论，例如盖奥托理论，不太可能作为来自弱耦合 规范理论的RG流的红外不动点出现。
