A simple, cubic lattice of planar rotators coupled via nearest neighbor bonds with random sign has been investigated on the basis of the lattice gauge theory. At low temperatures this spin glass problem is transformed into a simpler problem of random distribution of monopoles over the dual lattice sites. A rigorous expression for the Edward-Anderson's q has been obtained in this monopole formalism. It is concluded that q is very small, if not vanishing, as compared with 1 even in the low temperature limit. This means that the susceptibility diverges as x ∝1/T.
