 rf52880 over a rational function. The path integral is computed as a residue. The sum of N_(G,b) over all branch types b of sum d gives the The sum of N_(G,b) over all branch types b of sum d gives N_(G,d)*|Aut(G)|, with the Gromov-Witten invariant N_(G,d) of degree d stable maps from a genus g curve of topological type G to the elliptic curve. THEORY:  Computes @* - the Gromov-Witten of a given propagator P, or @* - the invariant N_(G,d) where d is the degree of the covering, or @* - the Gromov-Witten invariant of a given propagator P, or @* - the invariant N_(G,d)*|Aut(G)| where d is the degree of the covering, or @* - the number N_(G,b) of coverings with source G and target an elliptic curves with branch type a over a
