描述了二维非线性 $\ensuremath{\sigma}$ 模型的超对称形式；主要目的是进一步探讨$\ensuremath{\sigma}$模型与四维Yang-Mills理论之间的类比。在三个分量的情况下，该理论包含扩大的超对称代数，相当于普通的 $\ensuremath{\sigma}$ 模型，并具有赝粒子之间的额外对数相互作用。
A supersymmetric form of the two-dimensional nonlinear $\ensuremath{\sigma}$ model is described; the primary purpose is to explore further the analogy between the $\ensuremath{\sigma}$ model and four-dimensional Yang-Mills theory. In the case of three components, the theory contains an enlarged supersymmetry algebra and is equivalent to the ordinary $\ensuremath{\sigma}$ model with an additional logarithmic interaction between pseudoparticles.
