Consider classical Yang--Mills theory with quark sources placed in the background of a non-Abelian ’t Hooft--Polyakov monopole or a generalization thereof. Adler's monopole-backgro…

In four dimensions, consider non-Abelian Yang–Mills theories with inverse coupling constant $\beta$, a parameter governing the amount of order or disorder in the system. Area-law c…

Let $G$ be the gauge group and let the nontrivial Yang–Mills theory on Minkowskian spacetime $\mathbf{R}^{1,3}$ be the theory whose existence and quantization are asserted by the Y…

Let $l$ be a closed loop in the lattice and let $W_l=\operatorname{Tr}(Q_{e_1}Q_{e_2}\cdots Q_{e_n})$ be its Wilson loop variable. Let the minimum surface area enclosed by $l$ mean…
