Outline of Final Research Achievements

We obtained some results on moduli of semi-stable sheaves on K3 surfaces and abelian surfaces. In particular we described the local structure of the singular points and get an example of strange duality. We also proved Kawamata-Morrison's cone conjectures for two series of irreducible symplectic manifolds of Beauville.
For moduli spaces of stable sheaves on Enriques surfaces, we described the condition for the non-emptyness. We also obtained some results on the birational geometry of the moduli spaces by using Bridgeland stability conditions.

Academic Significance and Societal Importance of the Research Achievements

安定層とそのモジュライ空間は微分幾何やYang-Mills理論(インスタントン)と関係し、様々な立場から研究されてきた。本研究では多くのよい性質をもつ曲面であるK3曲面、アーベル曲面、Enriques曲面に対し、そのモジュライ空間の性質を調べた。とくにEnriques曲面上の安定層についてはこれまで研究があまり進んでいなかったが、この研究で安定層の存在性やモジュライの既約性など基本的な問題に成果を得ることができた。
