Les caractéristiques topologiques d'un domaine de sont analysées ici à l'aide des groupes d'homologie du premier et second ordre. La topologie algébrique et une factorization particulière de type dans peuvent être utilisées afin de savoir si est connexe et simplement connexe, de même que pour vérifier si une discrétisation de par éléments simpliciaux a été bien réalisée.
The topological features of a given domain in are here analyzed by means of the homology groups of first and second order. Algebraic topology together with a particular type factorization in can be used to know whether is connected and simply connected, as well as to check if a given discretization of by means of simplices has been correctly realized.
