A Multi-Parameter Method for Nonlinear Least-Squares Approximation,inear least-squares method works on ℝ., it is shown that the additional computational requirements consist of . − 1 gradient evaluations plus .(. · .) operations. The application to discrete rational approximation is discussed, and numerical examples are given.

Converse Theorems for Approximation on Discrete Sets II, of the known results to approximation on a sequence of discrete sets instead of an interval. The main tools are upper estimates of an .. norm in terms of an .. norm for the three classes of approximating functions in consideration.

Constructive Multivariate Approximation with Sigmoidal Functions and Applications to Neural Networkknown mapping existence theorem for three-layer feedforward neural networks. At the end, we apply our operators, resp. networks, to a special test function in order to get some concrete idea of their behaviour.

Quasi-Kernel Polynomials and Convergence Results for Quasi-Minimal Residual Iterations,l polynomials. In particular, we derive bounds for the norms of quasi-kernel polynomials. These results are then applied to obtain convergence theorems both for the QMR method, and for a transpose-free variant of QMR, the TFQMR algorithm.

Approximation by Multivariate Splines: an Application of Boolean Methods,an be applied to noncommutative operators. Based on this theory, an explicit quasi-interpolant is constructed so that it gives rise to an efficient scheme of approximation by multivariate smooth splines. This scheme is shown to achieve the optimal rate of approximation.
