Numerical integration of 2-D integrals based on local bivariate \(C^1\) quasi-interpolating splines
The authors study cubature formulas based on bivariate \(C^1\) local polynomial splines with a four directional mesh. The method proposed is applied to the numerical evaluation of two-dimensional singular integrals. Some numerical results, convergence properties and error bounds are given.
