摘要

本文的主要结果是构造了准极化投影曲面堆上稳定束的相对模距。为此，我们采用了alper提出的良模空间理论。作为推论，我们将相对奇异二象态射推广到准极化K3表面的焦点。

Moduli spaces of stable sheaves over quasi-polarized surfaces, and the relative Strange Duality morphism

The main result of the present paper is a construction of relative moduli spaces of stable sheaves over the stack of quasipolarized projective surfaces. For this, we use the theory of good moduli spaces, whose study was initiated by Alper. As a corollary, we extend the relative Strange Duality morphism to the locus of quasipolarized K3 surfaces.
