In this thesis, we study algorithms for a problem of finding relations in one or severalvariables. It generalizes that of computing a solution to a system of linear modularequations over a polynomial ring, including in particular the computation of Hermite-Padéapproximants and bivariate interpolants. Rather than a single solution, we aim atcomputing generators of the solution set which have good properties.Precisely, the input of our problem consists of a finite-dimensional module given bythe action of the variables on its elements, and of some elements of this module; the goalis to compute a Gröbner basis of the module of syzygies between these elements. In termsof linear algebra, the input describes a matrix with a type of Krylov structur...
