Invariant de nœuds — Les deux nœuds sont les mêmes, leur invariant est donc identique. En théorie des nœuds, un invariant de nœuds est une quantité définie pour chaque nœud qui est la même pour tous les nœuds équivalents. On parlera d équivalence lorsqu on peut… … Wikipédia en Français
Finite type invariant — In the mathematical theory of knots, a finite type invariant is a knot invariant that can be extended (in a precise manner to be described) to an invariant of certain singular knots that vanishes on singular knots with m + 1 singularities and… … Wikipedia

List of knot theory topics — Knot theory is the study of mathematical knots. While inspired by knots which appear in daily life in shoelaces and rope, a mathematician s knot differs in that the ends are joined together so that it cannot be undone. In precise mathematical… … Wikipedia

History of knot theory — For thousands of years, knots have been used for basic purposes such as recording information, fastening and tying objects together. Over time people realized that different knots were better at different tasks, such as climbing or sailing. Knots … Wikipedia
