• Valentin Tonita: K-theoretic GW invariants
    I will introduce K-theoretic GW invariants and the generating function for genus 0 invariants (the big J-function). Its graph gives rise to a Lagrangian cone \mathcal{L} in a symplectic vector space ( the K-theoretic Fock space) which enjoys properties analogous to the cone of cohomological theories. I will give a characterization of points on the cone \mathcal{L}. In particular this shows how K-theoretic GW invariants can be computed from cohomological ones.
