标题： The Donaldson-Witten Invariants in Pure QCD with Order and Disorder 't Hooft-like Operators

摘要： 我们研究了纯四维 \$ \mathrm\{${\rm SU}(2)$\} \$ 高斯-迈尔斯理论加上 \$\theta\$-项的一阶形式化。我们通过规范不变的非局域算符描述了类似于't Hooft的电通量和磁通量算符相关的Green函数。这些Green函数与Witten的四流形不变量有关。 显示英文摘要

摘要： We study the first-order formalism of pure four-dimensional ${\rm SU}(2)$ Yang--Mills theory with theta-term. We describe the Green functions associated to electric and magnetic flux operators \`a la 't~Hooft by means of gauge-invariant non-local operators. These Green functions are related to Witten's invariants of four-manifolds.
