Abstract

The system of unoriented tangle equations [Formula: see text] and [Formula: see text] is completely solved for the tangles U and [Formula: see text] as a function of [Formula: see text] where K 1 and K 2 are 4-plats, and [Formula: see text] and [Formula: see text] rational tangles such that |f 1 g 2 - g 1 f 2 | > 1. As an application, it is completely determined when one 4-plat can be obtained from another 4-plat via a signed crossing change.
