Abstract:

Let ${\{ {u_n}\} _{n \in \mathbb {Z}}}$ be a linear recurrence sequence. Given $a \ne 0, b \ne 0$, and natural $k \ne l$, we study equations as indicated in the title in unknowns $n,m$. It turns out that under natural conditions on the sequence $\{ {u_n}\}$, there are only finitely many solutions.
