Semisimple FJRW theory of polynomials with two variables
Amanda Francis, Weiqiang He, Yefeng Shen
We study the Dubrovin-Frobenius manifold in the Fan-Jarvis-Ruan-Witten theory of Landau-Ginzburg pairs $(W, \<J\>)$, where is an invertible nondegenerate quasihomogeneous polyn…

Seiberg Duality conjecture for star-shaped quivers and finiteness of Gromov-Witten thoery for D-type quivers
Weiqiang He, Yingchun Zhang
This is the second work on Seiberg Duality. This work proves that the Seiberg duality conjecture holds for star-shaped quivers: the Gromov-Witten theories for two mutation-related…

Cluster algebras and quantum cohomology rings: A-type
Weiqiang He, Yingchun Zhang
We construct a cluster algebra structure within the quantum cohomology ring of a quiver variety associated with an -type quiver. Specifically, let d…
