Résumé

We consider a family of quadrilateral or hexahedral mixed $h p$ -finite elements for an incompressible flow problem with $Q_{r}$ -elements for the velocity and discontinuous $P_{r - 1}$ -elements for the pressure where the order $r$ can vary from element to element between $2$ and an arbitrary bound. For multilevel adaptive grids with hanging nodes and a sufficiently small mesh size, we prove the inf-sup condition uniformly with respect to the mesh size and the polynomial degree.
