Wavelet/FEM coupling by the mortar method

S. Bertoluzza, S. Falletta and V. Perrier

{We propose and analyze in an abstract framework a mortar method with approximate constraint, based on replacing the ``master side'' function appearing in the weak continuity condition with its projection on a suitably chosen auxiliary space. We show how to choose the auxiliary space in such a way that such a technique can be applied for computing the weak continuity constraints arising in the framework of the wavelet/FEM coupling.
