Perspective and open problems on birational properties and singularities of moduli scheme of sheaves on surfaces

Kimiko Yamada

For complex projective smooth surface $X$ , let $M$ be the coarse moduli scheme of rank-two stable sheaves with fixed Chern classes. Grasping the birational structure of $M$ , for ex…

The Kodaira dimension and singularities of moduli of stable sheaves on some elliptic surfaces

Kimiko Yamada

Let $X$ be an elliptic surface over $P^{1}$ with $κ (X) = 1$ , and $M = M (c_{2})$ be the moduli scheme of rank-two stable sheaves $E$ on $X$ with $(c_{1} (E), c_{2} (E)) = (0, c_{2})$ in $\operato…

Singularities and Kodaira dimension of moduli scheme of stable sheaves on Enriques surfaces

Kimiko Yamada

Let M be a moduli scheme of stable sheaves with fixed Chern classes on an Enriques surface or a hyper-elliptic surface. If its expected dimension is 7 or more, then M admits only c…

Finiteness of isomorphic classes in the set of moduli schemes of sheaves on a surface

Kimiko Yamada

When a non-singular complex projective surface $X$ satisfies that $K_{X} \sim 0$ , we shall show that there are only finitely many isomorphic classes as abstract schemes in the set of…

Flips and variation of moduli schemes of sheaves on a surface

Kimiko Yamada

Let $H$ be an ample line bundle on a non-singular projective surface $X$ , and $M (H)$ the coarse moduli scheme of rank-two $H$ -semistable sheaves with fixed Chern classes on $X$ . We…

Desingularization of some moduli scheme of stable sheaves on a surface

Kimiko Yamada

Let $X$ be a nonsingular projective surface over an algebraically closed field with characteristic zero, and $H_{-}$ and $H_{+}$ ample line bundles on $X$ separated by only one wall of…
