An Estimate of Genus of Links

Abstract

By using the Seiberg-Witten invariant of 3-dimentional manifolds, we obtain an estimate of genus of links in the three shere. Keywords: the genus of links, the Seiberg-Witten invariant, the Alexander polynomial. *M. A. is supported by the JSPS Reseach Fellowship for Young Scientist. 405 J.
