FUSION AND SELF SHARP EQUIVALENCE OF LINKS

摘要

J. W. Milnor introduced a local move called the link-homptopy and it is an important tool for the classification of links. Recently several local moves of links whose concepts are stronger than that of link-homotopy are defined. And the properties of these moves are studied and applied to the classification of links. In this paper, we discuss a local move called the #-move and prove some properties of it and apply them to the classification of links obtained by fusions.
