Be more explicit about eventually-periodic case

Latest comment: 3 years ago1 comment1 person in discussion

Two possible improvements to this article:

• First, I think we should update the article to be clearer about the case of sequences like ${\displaystyle 1,0,0,0,\ldots }$ . This is allowed as a constant-recursive sequence according to the current text (see Eventually periodic sequences) but sections like Characterization in terms of exponential polynomials do not apply for such sequences.

• Second, the article should clearly place itself relative to linear difference equation. These are basically the same concept. I think the latter article is excluding the eventually-periodic case, though. And maybe we should here too... best idea would be to dig up a reference textbook and see how they define it.

Thoughts? Happy to make some of these changes when I get the chance. Caleb Stanford (talk) 19:00, 7 November 2021 (UTC)Reply
