Abstract: Let M be a connected, compact, orientable 3-manifold with \(b_1(M)>1\), whose boundary (if any) is a union of tori. Our main result is the inequality \({\parallel \phi \parallel}_A \le {\parallel \phi \parallel}_T\) between the Alexander norm on \(H^1(M,\mathbb{Z})\), defined in terms of the Alexander polynomial, and the Thurston norm, defined in terms of the Euler characteristic of embedded surfaces. (A similar result holds when \(b_1(M)=1\).) Using this inequality we determine the Thurston norm for most links with 9 or fewer crossings.
