We examine the problem of determining which representations of the bra
id group on a Riemann surface and carried by the wave function of a qu
antized Abelian Chern-Simons theory interacting with spinless non-dyna
mical matter. We generalize the quantization of Chern-Simons theory to
the case where the coefficient of the Chern-Simons term, k, is ration
al (for a set of rational charges), the Riemann surface has arbitrary
genus, and the total matter charge is non-vanishing. We find an explic
it solution of the Schrodinger equation. We find that the wave functio
ns carry a representation of the braid group as well as a dual project
ive representation of the discrete group of large gauge transformation
s. We find a Fundamental constraint which relates the charges of the p
articles, q(i), the coefficient k and the genus of the manifold, g:q(i
)(Q + q(i)(g - 1))/k is integer (where Q is the total charge). (C) 199
