Abstract: We will discuss some known problems concerning the arithmetic of linear recurrent sequences (e.g. defined over integers). First, given two linear recurrences defined over a number field, one can ask whether the quotient of them is also a linear recurrence. We are also interested in the gcd of two linear recurrences and the d-th root of a linear recurrence. In this talk, our goal is to give an overview of the developments of linear recurrences along the work of van der Poorten, Corvaja-Zannier and Levin as well as the corresponding problems for complex entire functions.
