具有有限多有限复迭和有限循环复迭的3维流形

3-Manifolds with Finitely Many Finite Coversor Finite Cyclic Covers

本文给出基本群为剩余有限的紧致３维流形何时有有限多有限复迭，何时有有限多有限循环复迭的充要条件．

We determine at what occasion while the compact 3-manifolds with residually finite groups have only finitely many finite covers, and while those have only finitely many finite cyclic covers.
