四维的杨-米尔斯拉格朗日量在较低的维度上隐含了相应的结构。以零能量动量张量和有限作用量为特征的瞬子作为一阶耦合方程的解出现。对于阿贝尔情形，所有这些解都由非线性Poisson-Boltzmann方程决定。
The four-dimensional Yang-Mills Lagrangian implies corresponding structures in lower dimensions. Instantons, characterized by a zero energy-momentum tensor as well as finite action, emerge as the solutions of coupled first order equations. For the Abelian case all such solutions are determined by the non-linear Poisson-Boltzmann equation.
