Topological String Partition Functions as Equivariant Indices

Jun Li, Kefeng Liu, Jian Zhou

We propose to use the identification of topological string partition functions as equivariant indices on framed moduli spaces of instantons to study the Gopakumar-Vafa conjecture f…

The Existence of Supersymmetric String Theory with Torsion

Jun Li, Shing-Tung Yau

We derived an existence criterion to the Supersymmetric String Theory with Torsion proposed by Strominger and proved the existence of such theory for a class of Calabi-Yau threefol…

Vanishing of the top Chern classes of the moduli of vector bundles

Young-Hoon Kiem, Jun Li

Let $Y$ be a smooth projective curve of genus $g \geq 2$ and let $M_{r, d} (Y)$ be the moduli space of stable vector bundles of rank $r$ and degree $d$ on $Y$ . A classical conjecture o…

Desingularizations of the moduli space of rank 2 bundles over a curve

Young-Hoon Kiem, Jun Li

Let $X$ be a smooth projective curve of genus $g \geq 3$ and $M_{0}$ be the moduli space of rank 2 semistable bundles over $X$ with trivial determinant. There are three desingularizati…

A Degeneration formula of GW-invariants

Jun Li

This is the second part of the paper "A degeneration of stable morphisms and relative stable morphisms", (math.AG/0009097). In this paper, we constructed the relative Gromov-Witten…

A degeneration of stable morphisms and relative stable morphisms

Jun Li

The introduction is modified in the revised version. Also, many typos and errors were corrected. Let $W \to C$ be degeneration of smooth varieties so that the special fiber has norm…
