Cohomological field theories (CohFTs) were defined in the mid 1990s by Kontsevich and Manin to capture the formal properties of the virtual fundamental class in Gromov-Witten theory. A beautiful classification result for semisimple CohFTs (via the action of the Givental group) was proven by Teleman in 2012. The Givental-Teleman classification can be used to explicitly calculate the full CohFT in many interesting cases not approachable by earlier methods. My goal here is to present an… Expand
HIGHER GENUS GROMOV – WITTEN THEORY OF Hilb n ( C 2 ) AND CohFTs ASSOCIATED TO LOCAL CURVES
We study the higher genus equivariant Gromov–Witten theory of the Hilbert scheme of n points of C2. Since the equivariant quantum cohomology, computed by Okounkov and Pandharipande [Invent. Math. 179Expand
Cohomological field theories with non-tautological classes
A method of constructing Cohomological Field Theories (CohFTs) with unit using minimal classes on the moduli spaces of curves is developed. As a simple consequence, CohFTs with unit are found whichExpand
Gromov-Witten classes of K3 surfaces
We study the cycle-valued reduced Gromov-Witten theory of a nonsingular projective K3 surface. For primitive curve classes, we prove that the correspondence induced by the reduced virtual fundamentalExpand
The Hilb/Sym correspondence for C2: descendents and Fourier-Mukai
We study here the crepant resolution correspondence for the torus equivariant descendent Gromov-Witten theories of Hilb(C2) and Sym(C2).The descendent correspondence is obtained from our previousExpand
Crepant resolution and the holomorphic anomaly equation for [C3/Z3]
We study the orbifold Gromov-Witten theory of the quotient C^3/Z_3 in all genera. Our first result is a proof of the holomorphic anomaly equations in the precise form predicted by B-model physics.Expand

On factorization and vector bundles of conformal blocks from vertex algebras
Modules over conformal vertex algebras give rise to sheaves of coinvariants and conformal blocks on moduli of stable pointed curves. Here we prove the factorization conjecture for these sheaves. OurExpand
