Abstract

A Z-linkless embedding of a graph is an embedding in 3-space such that each pair of disjoint circuits has zero linking number. In this paper we present polynomial-time algorithms to compute a Z-linkless embedding of a graph provided the graph has one and to test whether an embedding of a graph is Z-linkless or not.
