THE WU-YANG AMBIGUITY REVISITED

Several examples are given of continuous families of SU (2) vector potentials A(i)a(x) in 3 space dimensions which generate the same magnetic field B(ai)(x) (with det B not-equal 0). These Wu-Yang families are obtained from the Einstein equation R(ij) = -2G(ij) derived recently via a local map of the gauge field system into a spatial geometry with 2-tensor G(ij) = B(a)(j)B(a)j det B and connection GAMMA(jk)i with torsion defined from gauge covariant derivatives of B.
