Devant le constat, tant en Belgique qu'en France, des faibles taux de réussite en premiêre année universitaire, nous avons cherché à dégager le profil des étudiants qui risquent de se trouver en situation d'échec en fin d'année. Ainsi ils

A Fredholm integral equation of the second kind in L1([a, b], C) with a weakly singular kernel is considered. Sufficient conditions are given for the existence and uniqueness of the solution. We adapt the product integration method proposed in C0 ([a

This paper deals with nonlinear Fredholm integral equations of the second kind. We study the case of a weakly singular kernel and we set the problem in the space L 1 ( [ a , b ] , C ) . As numerical method, we extend the product integration scheme fr

The singularity subtraction technique for computing an approximate solution of a linear weakly singular Fredholm integral equation of the second kind is generalized to the case of a nonlinear integral equation of the same kind. Convergence of the seq

The classical way to tackle a nonlinear Fredholm integral equation of the second kind is to adapt the discretization scheme from the linear case. The Iterated projection method is a popular method since it shows, in most cases, superconvergence and i

This paper deals with superconvergence phenomena in general grids when projection-based approximations are used for solving Fredholm integral equations of the second kind with weakly singular kernels. Four variants of the Galerkin method are consider

In several applications needing the numerical computation of eigenvalues and eigenvectors we deal with strongly quasi-diagonal matrices. An iterative explicit method for this kind of problem is proposed here. Its convergence is proved by means of an

We provide an error estimate for the local mean projection approximation in Lp([0,τ∗]) for p∈[1,+∞[, in terms of the regularity of the underlying grid, and we apply it to the corresponding projection approximation of weakly singular Fredholm i
