That's the state of ML today I guess <shrug>. It's only as good as what it was trained on. In my experience, if you can't find something after engaging with google's search for a couple of minutes, refining your query and going on tangents, then it probably doesn't exist, or you're asking the wrong question. I think, but I'm not sure, that in your case your question is too broad. You need to be more specific. It's as if you asked "what are the possible things I can do with a for loop", the question is too broad, and it's sort of the wrong question. I guess you already tried, but for what you want, try querying scholar.google.com directly and playing around with the keywords. More concretely, did you mean lists as a in array in a programming language? Or vectors? If vectors, then you should say vectors and not lists. If lists as in the general concept in many programming languages, then there are 2 approaches: 1) Lists can be seen as a special/degenerate case of a graph. Which is sort of what ChatGPT was nudging you toward, mentioning trees in the results. In that case, you're interested in graph theory. 2) If you meant to analyze the possible actions that a program can run on lists (without considering them as a graph) take a look at Haskell, specifically how the various standard typeclasses are specialized on lists. You can start here, I guess: https://en.wikibooks.org/wiki/Haskell/Monoids https://en.wikibooks.org/wiki/Haskell/Monoids This is more general than "actions on lists", but this series of wiki articles give lists as an example for each standard typeclass. That's a mathematical treatment of lists by considering them as an embodiment of some mathematical concepts taken from abstract algebra, such as monads, monoids, etc.
