Multi-indice
En mathématiques, les multi-indices généralisent la notion d'indice entier en permettant d'envisager plusieurs variables entières pour une indexation. L'utilisation des multi-indices a pour but de simplifier les formules qu'on rencontre dans le calcul à plusieurs variables, que ce soit pour le calcul polynomial ou en analyse vectorielle. Un multi-indice de taille n est un vecteur à coefficients entiers positifs.
Corecursion
In computer science, corecursion is a type of operation that is to recursion. Whereas recursion works analytically, starting on data further from a base case and breaking it down into smaller data and repeating until one reaches a base case, corecursion works synthetically, starting from a base case and building it up, iteratively producing data further removed from a base case. Put simply, corecursive algorithms use the data that they themselves produce, bit by bit, as they become available, and needed, to produce further bits of data.
