Gauss-Galerkin quadrature rules for quadratic and cubic spline spaces and their application to isogeometric analysis (Computer-Aided Design, 2016-07-01)We introduce Gaussian quadrature rules for spline spaces that are frequently used in Galerkin discretizations to build mass and stiffness matrices. By definition, these spaces are of even degrees. The optimal quadrature ...
