Multivariate polynomial equations with multiple zeros solved by matrix eigenproblems
The eigenproblem method calculates the solutions of systems of polynomial equations \( f_1(x_1, \ldots , x_s)=0,\ldots,f_m(x_1, \ldots , x_s)=0\) . It consists in fixing a suit...

The defect correction principle and discretization methods
Recently, a number of closely related techniques for error estimation and iterative improvement in discretization algorithms have been proposed. In this article, we expose the common structural principle of al...

Numerical approximation of Fourier-transforms
A method has been presented for the numerical evaluation of the integrals occuring in Fourier transformation which is based upon the approximation of the transform as a function of its variable co. The numeric...
