摘要：

In this paper product quadrature rules based on quasi-interpolating splines are proposed and convergence results are proved for bounded integrands. Convergence results are also proved for sequences of Cauchy principal value integrals of these quasi-interpolating splines. Some comparisons with other methods and numerical examples are given.
