Infinity of Zeros of Recurrence Sequences

Abstract

The purpose of this work is to study the zeros of linear recurrence sequence, with constant coefficients. We give a simple proof of well known Skolem-Mahler-Lech theorem. The advantage of this work is similar to the one done by V. Halava and collaborators, but in a simple way. We study the problem when the general term of the recurrent sequence is of exponential polynomial with some initial conditions that simplify the problem.
