摘要

We develop new techniques to study regularity questions for moduli spaces of pseudoholomorphic curves that are multiply covered. Among the main results, we show that unbranched multiple covers of closed holomor-phic curves are generically regular, and simple index 0 curves in dimen-sions greater than four are generically super-rigid, implying, e.g., that the Gromov-Witten invariants of Calabi-Yau 3-folds reduce to sums of local in-variants for finite sets of embedded curves. We also establish partial results on super-rigidity in dimension four and regularity of branched covers, and briefly discuss the outlook for bifurcation analysis. The proofs are based on a general stratification result for moduli spaces of multiple covers, framed in terms of a representation-theoretic splitting of Cauchy-Riemann operators with symmetries.
