AI总结:
本文研究了秩为3的离散子群商空间上酉平坦线丛的紧支撑上同调群,并证明了在特定类别下该同调群消没,包含无穷多例使其非Hausdorff且无穷维的例子。
摘要:
设 $X$ 为复欧几里得空间 $\mathbb{C}^2$ 模秩为 $3$ 的离散子群得到的复曲面。我们研究 $X$ 上酉平坦线丛 $E$ 的紧支撑上同调群 $H_0^1(X, E)$。我们证明了此类对 $(X, E)$ 中特定一类的 $H_0^1(X, E)$ 消没,此类包含无穷多例使 $H^1(X, E)$ 非 Hausdorff 且无穷维的例子。
英文摘要:
Let $X$ be a complex surface obtained as the quotient of the complex Euclidean space $\mathbb{C}^2$ by a discrete subgroup of rank $3$. We investigate the cohomology group $H_0^1(X, E)$ with compact support for a unitary flat line bundle $E$ over $X$. We show the vanishing of $H_0^1(X, E)$ for a certain class of such pairs $(X, E)$, which includes infinitely many examples such that $H^1(X, E)$ is non-Hausdorff and infinite dimensional.
