In this paper the authors are concerned with spectral properties of stiffness matrices in the context of isogeometric analysis for second order PDEs are analyzed. Non-singularity, conditioning, spectral distribution in the Weil sense, clustering of eigenvalues are particularly investigated for 1D and 2D problems.
