Functorial relationships between quantum cohomology of complete and partial flag varieties, (II)
Changzheng Li
We show a canonical injective morphism from the quantum cohomology ring QH(G/P) to the associated graded algebra of QH(G/B), which is with respect to a nice filtration on QH(G/B) i…
Quantum Pieri rules for tautological subbundles
Naichung Conan Leung, Changzheng Li
We give quantum Pieri rules for quantum cohomology of Grassmannians of classical types, expressing the quantum product of Chern classes of the tautological subbundles with general…
Lattice point counting via Einstein metrics
Ziming Nikolas Ma, Naichung Conan Leung
We obtain a growth estimate for the number of lattice points inside any Q-Gorenstein cone. Our proof uses the result of Futaki-Ono-Wang on Sasaki-Einstein metric for the toric Sasa…
Instantons in G2 manifolds from J-holomorphic curves in coassociative submanifolds
Naichung Conan Leung, Xiaowei Wang, Ke Zhu
In G2 manifolds, 3-dimensional associative submanifolds (instantons) play a role similar to J-holomorphic curves in symplectic geometry. In [21], instantons in G2 manifolds were co…
Affine ADE bundles over complex surfaces with p_g=0
Yunxia Chen, Naichung Conan Leung
We study simply-laced simple affine Lie algebra bundles over complex surfaces X. Given any Kodaira curve C in X, we construct such a bundle over X. After deformations, it becomes t…
