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... https://chefesquipmenters.shop/product-category/pull-through-knife-sharpeners/
