  skos:definition """En mathématiques discrètes, et notamment en combinatoire, un treillis de Tamari, introduit par le mathématicien Dov Tamari, est un ensemble partiellement ordonné dont les éléments sont les différentes façons de grouper une suite d'objets en paires par parenthésage ; par exemple, pour la suite <i>abcd</i> de quatre objets, il y a cinq groupements possibles, qui sont : ((<i>ab</i>)<i>c</i>)<i>d</i>, (<i>ab</i>)(<i>cd</i>), (<i>a</i>(<i>bc</i>))<i>d</i>, <i>a</i>((<i>bc</i>)<i>d</i>), et <i>a</i>(<i>b</i>(<i>cd</i>)). 
<br/>(Wikipedia, L'Encylopédie Libre, <a href="https://fr.wikipedia.org/wiki/Treillis_de_Tamari">https://fr.wikipedia.org/wiki/Treillis_de_Tamari</a>)"""@fr, """In mathematics, a Tamari lattice, introduced by Dov Tamari (1962), is a partially ordered set in which the elements consist of different ways of grouping a sequence of objects into pairs using parentheses; for instance, for a sequence of four objects <i>abcd</i>, the five possible groupings are: ((<i>ab</i>)<i>c</i>)<i>d</i>, (<i>ab</i>)(<i>cd</i>), (<i>a</i>(<i>bc</i>))<i>d</i>, <i>a</i>((<i>bc</i>)<i>d</i>), and <i>a</i>(<i>b</i>(<i>cd</i>)). Each grouping describes a different order in which the objects may be combined by a binary operation; in the Tamari lattice, one grouping is ordered before another if the second grouping may be obtained from the first by only rightward applications of the associative law (<i>xy</i>)<i>z</i> = <i>x</i>(<i>yz</i>). For instance, applying this law with <i>x</i> = <i>a</i>, <i>y</i> = <i>bc</i>, and <i>z</i> = <i>d</i> gives the expansion (<i>a</i>(<i>bc</i>))<i>d</i> = <i>a</i>((<i>bc</i>)<i>d</i>), so in the ordering of the Tamari lattice (<i>a</i>(<i>bc</i>))<i>d</i> ≤ <i>a</i>((<i>bc</i>)<i>d</i>).
