Properties of Gromov-Witten invariants defined via global Kuranishi charts
submitted
We prove that the Gromov-Witten invariants constructed by Hirschi-Swaminathan satisfy the Kontsevich-Manin axioms. The construction extends to the equivariant setting and we prove a localisation formula for the equivariant Gromov-Witten invariants of certain Hamiltonian torus manifolds.
On Donaldson’s 4-6 question
joint with Luya Wang, submitted
We prove that the examples of Smith and McMullen-Taubes provide infinitely many counterexamples to one direction of the Donaldson four-six question and the closely related Stabilising Conjecture. In the other direction we show that manifolds that be-
come deformation equivalent after one stabilisation have the same Gromov-Witten invariants.
Lagrangian intersections and cuplength in generalised cohomology
joint with Noah Porcelli, accepted for publication in Mathematical Research Letters
Using generalised cohomology theories we find better lower bounds on the number
of intersection points of two Lagrangians in the absence of transversality conditions.
