论文摘要
该论文致力于适应作者在有限的共同体学理论中对无限链的leray定理方法的改编。主要的结果是格罗莫夫消失的限制定理的一种更强，更一般的形式，以及他削减定理的第一部分的概括。证明是基本的。
The paper is devoted to an adaptation of author's approach to Leray theorems in bounded cohomology theory to infinite chains. The main results are a stronger and more general form of Gromov's Vanishing-finiteness theorem and a generalization of the first part of his Cutting-of theorem. The proofs are elementary.
