3-流形群的余秩猜想

The co-rank conjecture for 3-manifold groups

Christopher J. Leininger, Alan W. Reid

摘要:

在本文中,我们构建了封闭和非紧有限体积双曲流形的显式例子,它提供了反例的猜想,3-流形组的co-rank(也称为切割数)是有界的第一个贝蒂数的三分之一以下。

英文摘要:

In this paper we construct explicit examples of both closed and non-compact finite volume hyperbolic manifolds which provide counterexamples to the conjecture that the co-rank of a 3-manifold group (also known as the cut number) is bounded below by one-third the first Betti number.
