The aim of this note is to deduce error estimates for a fully-discrete finite element method approximation of a kind of degenerate mixed parabolic equations. The obtained results consider regularity assumptions about the main variable according to the degenerate character of the problem, given by the term involving the time-derivative, which is represented with a non-invertible linear operator
Le but de cette note est de déduire des estimations d’erreur pour une approximation par la méthode des éléments finis entièrement discrets d’un type d’équations paraboliques mixtes dégénérées. Les résultats obtenus considèrent des hypothèses de régularité sur la variable principale selon le caractère dégénéré du problème, donné par le terme impliquant la dérivée temporelle, qui est représentée par un opérateur linéaire non inversible
