WebIndeed, Seiberg and Witten showed that this infrared limit of the above theory is equivalent to a weakly-coupled U ( 1) -gauge theory (the S U ( 2) -gauge group is spontaneously broken down to the maximal torus). Perhaps here is where a better understanding would be desirable (buzzwords 'asymptotic freedom' and 'symmetry breaking' appear).

"Web1. Seiberg-Witten invariants: recap of definition Let Xbe a closed smooth oriented 4-manifold. Then Xadmits a spinc structure, i.e. a lift of the frame bundle (a principal SO(4)-bundle) to a principal Spinc(4)-bundle. We write Spinc(X) to denote the collection of spincstructures on X. Recall that Spinc(4) = U(1) Spin(4)= 1; " - Spin geometry and seiberg-witten invariants

WebThe Seiberg-Witten invariants of X constitute a map from the set of equivalence classes of SpinC structures on X (covering the frame bundle) to the integers. (These invariants are deﬁned by counting (in a suitable sense) the solutions to a natural system of diﬀerential equations on X which are deﬁned using a SpinC structure.) Web4 T.
