我们提出了好裤同源性的概念,并证明了它与闭表面上的标准同源性是一致的。(好裤子是指裤子的长度几乎等于某个大数字R > 0。)结合我们之前关于曲面子群定理的工作,我们得到了Ehrenpreis猜想的一个证明。
We develop the notion of the good pants homology and show that it agrees with the standard homology on closed surfaces. (Good pants are pairs of pants whose cus have the length nearly equal to some large number R > 0.) Combined with our previous work on the Surface Subgroup Theorem, this yields a proof of the Ehrenpreis Conjecture.
