确定了具有K3目标空间的N=(4,4)弦理论的模空间，特别证明了离散对称群是特征为（4,20）的偶单模格的满积分正交群。该方法将经典的K3模空间理论与镜像对称理论相结合。从量子几何的角度对模空间进行了描述，并对代数K3曲面的镜像对称性进行了讨论。
The moduli space of N=(4,4) string theories with a K3 target space is determined, establishing in particular that the discrete symmetry group is the full integral orthogonal group of an even unimodular lattice of signature (4,20). The method combines an analysis of the classical theory of K3 moduli spaces with mirror symmetry. A description of the moduli space is also presented from the viewpoint of quantum geometry, and consequences are drawn concerning mirror symmetry for algebraic K3 surfaces.
