## Communicated by A. Kunoth Quasi-interpolation is very important in the study of the approximation theory and applications. In this paper, a multilevel univariate quasi-interpolation scheme with better smoothness using cubic spline basis on uniform partition of bounded interval is proposed. More
A new cubature rule for a parallelepiped domain is defined by integrating a discrete blending sum of C 1 quadratic spline quasi-interpolants in one and two variables. We give the weights and the nodes of this cubature rule and we study the associated error estimates for smooth functions. We compare
