Algebraic Geometry Seminar - Hsian-Hua Tseng
Title: A tale of four theoriesSpeaker: Hsian-Hua Tseng (Ohio State University)Abstract: Around a decade ago the following four $(\mathbb{C}^*)^2$-equivariant theories are proven to be equivalent:Gromov-Witten theory of $\mathbb{P}^1 \times \mathbb{C}^2$ relative to three fibers;Donaldson-Thomas theory of $\mathbb{P}^1 \times \mathbb{C}^2$ relative to three fibers;Quantum cohomology of Hilbert schemes of points on $\mathbb{C}^2$;Quantum cohomology of symmetric product stacks of $\mathbb{C}^2$.In this talk we'll discuss these four equivalence. We'll also sketch some new development, namely higher genus extensions of these equivalences (joint work with R. Pandharipande).Seminar URL: https://research.math.osu.edu/agseminar/

Title: A tale of four theories
Speaker: Hsian-Hua Tseng (Ohio State University)
Abstract: Around a decade ago the following four $(\mathbb{C}^*)^2$-equivariant theories are proven to be equivalent:
- Gromov-Witten theory of $\mathbb{P}^1 \times \mathbb{C}^2$ relative to three fibers;
- Donaldson-Thomas theory of $\mathbb{P}^1 \times \mathbb{C}^2$ relative to three fibers;
- Quantum cohomology of Hilbert schemes of points on $\mathbb{C}^2$;
- Quantum cohomology of symmetric product stacks of $\mathbb{C}^2$.
In this talk we'll discuss these four equivalence. We'll also sketch some new development, namely higher genus extensions of these equivalences (joint work with R. Pandharipande).
