On Orbifold Quantum Cohomology of Foldings of Resolutions
Jingxiang Ma
We compute the untwisted part of the -equivariant orbifold quantum cohomology of certain finite cyclic quotients of the minimal resolutions of Kleinian singulari…

Involution-equivariant topological recursion and mirror symmetry for the affine binary dihedral Calabi--Yau threefold
Bohan Fang, Zhuoming Lan, Jingxiang Ma
We prove a closed-string remodeling statement for the affine binary dihedral Calabi--Yau orbifold threefold , where is a binary dihed…

Dubrovin duality and mirror symmetry for ADE resolutions
Andrea Brini, Jingxiang Ma, Ian A. B. Strachan
We show that, under Dubrovin's notion of ''almost'' duality, the Frobenius manifold structure on the orbit spaces of the extended affine Weyl groups of type is dual,…
