Gromov-Witten Invariants via Algebraic Geometry
نویسنده
چکیده
Calculations of the number of curves on a Calabi-Yau manifold via an instanton expansion do not always agree with what one would expect naively. It is explained how to account for continuous families of instantons via deformation theory and excess intersection theory. The essential role played by degenerate instantons is also explained.

The Closed Topological Vertex via the Cremona Transform
We compute the local Gromov-Witten invariants of the “closed vertex”, that is, a configuration of three P’s meeting in a single triple point in a Calabi-Yau threefold. The method is to express the local invariants of the vertex in terms of ordinary Gromov-Witten invariants of a certain blowup of P and then to compute those invariants via the geometry of the Cremona transformation.
متن کاملSome properties of hypergeometric series associated with mirror symmetry
We show that certain hypergeometric series used to formulate mirror symmetry for Calabi-Yau hypersurfaces, in string theory and algebraic geometry, satisfy a number of interesting properties. Many of these properties are used in separate papers to verify the BCOV prediction for the genus one Gromov-Witten invariants of a quintic threefold and more generally to compute the genus one Gromov-Witte...
متن کاملElliptic Gromov-Witten Invariants And Virasoro Conjecture
The Virasoro conjecture predicts that the generating function of Gromov-Witten invariants is annihilated by infinitely many differential operators which form a half branch of the Virasoro algebra. This conjecture was proposed by Eguchi, Hori and Xiong [EHX2] and also by S. Katz [Ka] (see also [EJX]). It provides a powerful tool in the computation of Gromov-Witten invariants. In [LT], the author...
متن کاملKEVIN COSTELLO Definition
This is the first of two papers which construct a purely algebraic counterpart to the theory of Gromov-Witten invariants (at all genera). These GromovWitten type invariants depend on a Calabi-Yau A∞ category, which plays the role of the target in ordinary Gromov-Witten theory. When the Fukaya category of a compact symplectic manifold X is used, it is shown, under certain assumptions, that the u...
متن کاملThe Quantum Cohomology of Blow-ups of P and Enumerative Geometry
The enumerative geometry of curves in algebraic varieties has taken a new direction with the appearance of Gromov-Witten invariants and quantum cohomology. Gromov-Witten invariants originate in symplectic geometry and were first defined in terms of pseudo-holomorphic curves. In algebraic geometry, these invariants are defined using moduli spaces of stable maps. Let X be a nonsingular projective...
