Integers represented by binary recursive sequences
L. Hajdu, R. Tijdeman
This paper is the continuation of \cite{htl}, where we deal with Lucas sequences. Here we study integers represented by integer sequences which satisfy binary recursive relations.…

Integers represented by Lucas sequences
L. Hajdu, R. Tijdeman
In this paper we study the sets of integers which are -th terms of Lucas sequences. We establish lower- and upper bounds for the size of these sets. These bounds are sharp for $…
