Wavelet/FEM Coupling by the Mortar Method
Silvia Bertoluzza, Silvia Falletta, Valérie Perrier · Lecture notes in computational science and engineering · 2002
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.
