Alexander多项式的Mahler测度

Mahler measure of Alexander polynomials

Daniel S. Silver, Susan G. Williams

摘要:

设l是同调三维球面中d个连通分支的有向链环。对任意非负整数q,设l(q)是d-1个分量的连接,通过对l的第d个分量进行1/q运算得到。那么当q趋于无穷大时,l(q)的Alexander多项式的Mahler测度收敛于l的Alexander多项式的Mahler测度,只要l的其他分量与dth有非零的环绕数。另外,l(q)的Alexander多项式的Mahler测度有一个明确的但不同的极限行为.例子给出的链接的马勒措施的亚历山大多项式是小的。讨论了与双曲体积的可能联系。

英文摘要:

Let l be an oriented link of d components in a homology 3-sphere. For any nonnegative integer q, let l(q) be the link of d-1 components obtained from l by performing 1/q surgery on the dth component. Then the Mahler measure of the Alexander polynomial of l(q) converges to the Mahler measure of the Alexander polynomial of l as q goes to infinity, provided that some other component of l has nonzero linking number with the dth. Otherwise, the Mahler measure of the Alexander polynomial of l(q) has a well-defined bu different limiting behavior. Examples are given of links for which the Mahler measure of the Alexander polynomial is small. Possible connection with hyperbolic volume are discussed.
