"Big Quantum cohomology of orbifold spheres." https://arxiv.org/abs/2002.11180.https://hdl.handle.net/2144/42158We construct a Kodaira-Spencer map from the big quantum cohomology of a sphere with three orbifold points to the Jacobian ring of the mirror Landau-Ginzburg potential function. This is constructed via the Lagrangian Floer theory of the Seidel Lagrangian and we show that Kodaira-Spencer map is a ring isomorphism.en-USArticle587282
