Resumé: The main topic of this Ph.D. subject is to exploit the link between polynomials and linear recurrence relations of a sequence in order to accelerate either the computations of Gröbner bases for polynomial system solving or the guessing of all the recurrences satisfied by a multi-indexed sequence. To do so, we aim to thoroughly analyze and take advantage of the structure of the linear systems that appear in these computations. The main objective of this Ph.D. thesis is the design of fast algorithms for guessing linear recurrence relations, whether with constant or polynomial coefficients, in order to accelerate polynomial system solving or the description of the nature of the sequences coming from applications, such as combinatorics.
