描述This book contains plenary lectures given at the International Conference on Mathematical and Computational Modeling, Approximation and Simulation, dealing with three very different problems: reduction of Runge and Gibbs phenomena, difficulties arising when studying models that depend on the highly nonlinear behaviour of a system of PDEs, and data fitting with truncated hierarchical B-splines for the adaptive reconstruction of industrial models. The book includes nine contributions, mostly related to quasi-interpolation. This is a topic that continues to register a high level of interest, both for those working in the field of approximation theory and for those interested in its use in a practical context. Two chapters address the construction of quasi-interpolants, and three others focus on the use of quasi-interpolation in solving integral equations. The remaining four concern a problem related to the heat diffusion equation, new results on the notion of convexity in probabilistic metric spaces (which are applied to the study of the existence and uniqueness of the solution of a Volterra equation), the use of smoothing splines to address an economic problem and, finally, the analy

Richardson Extrapolation of Nyström Method Associated with a Sextic Spline Quasi-Interpolante second kind. For a sufficiently smooth kernel the method is shown to have convergence of order 8 and the . extrapolation is used to further improve this order to 9. Numerical examples are given to confirm the theoretical estimates.

Numerical Methods Based on Spline Quasi-Interpolating Operators for Hammerstein Integral Equationsolve Hammerstein integral equation. We present an error analysis of the approximate solutions and we show that the iterated solution of collocation type exhibits a superconvergence as in the case of the Galerkin method. Finally, we provide numerical tests, that confirm the theoretical results.

Superconvergent Methods Based on Cubic Splines for Solving Linear Integral EquationsIn this paper we propose two collocation methods, based on superconvergent cubic spline interpolant and quasi-interpolant, for approximating the solution of the second kind Fredholm integral equations. Convergence analysis is established. Some numerical examples are given to show the validity of the presented methods.
