Errata of the paper "Cellular chain complexes of universal covers of some 3-manifolds,"


$C^*(M;A)$ in Section 5 should be $C^*(\widetilde{M};A)$
Some $\alpha_i$ in Example 5.1 should be $f^*(\alpha)_i.$
In the paragraph before Theorem 3.1, I claimed "Since f∗ is a group isomorphism, there exists a unique element q_f satisfying...." But, that is not always true even if $T_f$ is a torus bundle. So, Theorem 3.1 is wrong. But, it is true if there is such q_f. I am sorry to say that I have no idea to correct Theorem 3.1 in general cases.
