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…

Blowing-ups describing the polarization change of moduli schemes of semistable sheaves of general rank

Kimiko Yamada

Let $H$ and $H^{'}$ be two ample line bundles over a smooth projective surface $X$ , and $M (H)$ (resp. $M (H^{'})$ ) the coarse moduli scheme of $H$ -semistable (resp. $H^{'}$ -semistable) sheav…

A sequence of blowing-ups connecting moduli of sheaves and the Donaldson polynomial under change of polarization

Kimiko Yamada

Let $H$ and $H^{'}$ be two ample line bundles over a nonsingular projective surface $X$ , and $M (H)$ (resp. $M (H^{'})$ ) the coarse moduli scheme of $H$ -semistable (resp. $H^{'}$ -semistable)…
