Abstract

We consider SU(N) gauge theories on a two dimensional torus with finite area, AA. Let Tμ(A)T_\mu(A) denote the Polyakov loop operator in the μ\mu direction. Starting from the lattice gauge theory on the torus, we derive a formula for the continuum limit of g1(T1(A))g2(T2(A))\langle g_1(T_1(A)) g_2(T_2(A)) \rangle as a function of the area of the torus where g1g_1 and g2g_2 are class functions. We show that there exists a class function ξ0\xi_0 for SU(2) such that ξ0(T1(A))ξ0(T2(A))>1\langle \xi_0(T_1(A)) \xi_0(T_2(A))\rangle > 1 for all finite area of the torus with the limit being unity as the area of the torus goes to infinity. Only the trivial representation contributes to ξ0\xi_0 as AA\to\infty whereas all representations become equally important as A0A\to 0.
