Un exemple d&#8217;entrelacs est donn\u00e9 par les anneaux sur la photo ci-contre. Cet entrelacs est apparu il y a bien longtemps \u00e0 plusieurs moments de l&#8217;histoire. On les appelle parfois les anneaux Borrom\u00e9ens en r\u00e9f\u00e9rence \u00e0 la famille italienne des Borromeo qui les utilisaient en d\u00e9coration de ses armoiries. Un entrelacs est un enchev\u00eatrement de plusieurs cordes ferm\u00e9es de fa\u00e7on \u00e0 ce qu&#8217;il n&#8217;y ait pas de bout. Un noeud est le cas o\u00f9 l&#8217;entrelacs ne poss\u00e8de qu&#8217;une corde.<\/p>\n<p style=\"text-align: justify\">Lorsque l&#8217;entrelacs consid\u00e9r\u00e9 est form\u00e9 de cordes non nou\u00e9es entre elles ou individuellement, on parle de l&#8217;entrelacs trivial. <img loading=\"lazy\" decoding=\"async\" class=\" size-medium wp-image-1261 alignright\" src=\"http:\/\/perso.math.univ-toulouse.fr\/hippocampe\/files\/2016\/06\/IMG_3931-300x225.jpg\" alt=\"IMG_3931\" width=\"300\" height=\"225\" srcset=\"https:\/\/perso.math.univ-toulouse.fr\/hippocampe\/files\/2016\/06\/IMG_3931-300x225.jpg 300w, https:\/\/perso.math.univ-toulouse.fr\/hippocampe\/files\/2016\/06\/IMG_3931-1024x768.jpg 1024w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>En d\u00e9formant les cordes d&#8217;un entrelacs mais sans les couper, on peut chercher \u00e0 savoir s&#8217;il est trivial ou non.

En effet, il est parfois possible de d\u00e9m\u00ealer des sacs de noeuds ! Lorsqu&#8217;il n&#8217;y a qu&#8217;une seule corde, la question devient : comment savoir si un noeud est le\u00a0noeud trivial ? C&#8217;est une des premi\u00e8res questions que l&#8217;on peut se poser sur les noeuds et les entrelacs et on ne sait toujours pas donner une r\u00e9ponse compl\u00e8te.<\/p>\n<p style=\"text-align: justify\">Apr\u00e8s de longues heures de r\u00e9flexion, les \u00e9l\u00e8ves du lyc\u00e9e Pierre d&#8217;Aragon ont pr\u00e9par\u00e9 des posters pour pr\u00e9senter leurs trouvailles.
