TOWARDS COERCIVE BOUNDARY ELEMENT METHODS FOR THE WAVE EQUATION
We discuss the ellipticity of the single layer boundary integral operator for the wave equation in one space dimension. This result not only generalizes the well-known ellipticity of the energetic boundary integral formulation in L2, but it also turns out to be a particular case of a recent result on …
