Abstract:
Three conditions equivalent to a two-bridge link having unlinking number one are given. As a corollary it is shown that an unknotting crossing appears in the minimal diagram of a two-bridge knot or link. In addition, the absolute value of the linking number of the components is computed for all unlinking number one two-bridge links.References
