Abstract
The properties of topological objects with fractional charge are studied. We first transform to new variables, in terms of which the lowest order contribution gives the fractional charge. We then gauge that fractional charge. Effects of the θ angle in two dimensions are studied. In particular arbitrary periods may be obtained. Induced extra charge due to θ turns out to be proportional to trθ. C and P violations due to θ may be arbitrarily small in some cases.
