Pieces of string or curves in three dimensional space may be knotted orbraided. This topological tool can be used to study certain types of nonlineardifferential equations. In particular, such an approach leads to forcingtheorems in the spirit of the famous 'period three implies chaos' for intervalmaps. We have identified three types of differen...
