Bertoluzza S., Falletta S., Perrier V. Wavelet/FEM Coupling by the Mortar Method. Technical report ercim.cnr.ian//2001-1228, 2001.
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.
