Reduced genus-one Gromov-Witten invariants

摘要: In a previous paper we described natural closed subset M 0 1,k(X,A; J) of the moduli space M1,k(X,A; stable genus-one J-holomorphic maps into symplectic manifold X. this generalize definition main component to spaces perturbed, in restricted way, maps. This generalization implies that J), just like carries virtual fundamental class and can be used define invariants. These truly invariants constitute part standard GromovWitten invariants, which arise from entire J). The new are more geometric compute GW-invariants complete intersections, as shown separate paper.
