Geometric Aspects of Lucas Sequences, II

Abstract

This article is a sequel of $\langle$Geometric aspects of Lucas sequences, I$\rangle$, which presents a way of viewing Lucas sequences in the framework of group scheme theory. This enables us to treat the Lucas sequences from a geometric and functorial viewpoint, which was suggested by Laxton $\langle$On groups of linear recurrences, I$\rangle$ and by Aoki-Sakai $\langle$Mod $p$ equivalence classes of linear recurrence sequences of degree 2$\rangle$. It is crucial in this work to employ the notion of quotients though at an elementary level.
