公理弱引力猜想预言了瞬子的存在，其作用量小于其电荷的适当单位。我们表明，猜想是满足的轴子-引力系统，如果我们假设的二元性约束的高阶导数校正除了正界遵循的么正性，解析性和本地化的UV散射振幅。另一方面，如果我们只假设正性界，则该猜想不成立。这提出了一个例子，弱引力猜想的推导需要更详细的紫外线信息比散射振幅的一致性。
The axionic weak gravity conjecture predicts the existence of instantons whose actions are less than their charges in appropriate units. We show that the conjecture is satisfied for the axion-dilaton-gravity system if we assume duality constraints on the higher derivative corrections in addition to positivity bounds which follow from unitarity, analyticity, and locality of UV scattering amplitudes. On the other hand, the conjecture does not follow if we assume the positivity bounds only. This presents an example where derivation of the weak gravity conjecture requires more detailed UV information than the consistency of scattering amplitudes.
