摘要
让 X 是一个非邢状紧凑复曲面,使得反锥线束具有半正曲率的光滑赫米特度量。对于定义了反偶函数除数的非星超曲面 Y,我们研究了补集(M=Xsetminus Y)的同调群(H^1(M, \mathcal {O}_M))。
$$\overline{\partial }$$ cohomology of the complement of a semi-positive anticanonical divisor of a compact surface
Let X be a non-singular compact complex surface such that the anticanonical line bundle admits a smooth Hermitian metric with semi-positive curvature. For a non-singular hypersurface Y which defines an anticanonical divisor, we investigate the \(\overline{\partial }\) cohomology group \(H^1(M, \mathcal {O}_M)\) of the complement \(M=X\setminus Y\).
