Hi! It’s Monday, my name is Colin and I am a mathematician. What can I help you with this week? Bonus points if it involves continued fractions.
@icecolbeveridge what is a sheaf (in math)? a friend tried explaining them to me a couple of years ago and I couldn't understand anything. I've had one semester each of basic category theory and real analysis.
@danielhglus Alas, that's not an area I know anything about, and a few minutes' reading hasn't enlightened me :-(
@danielhglus My doctorate was about the Sun's atmosphere -- a mix of geometry, numerical analysis, basic topology, vector calculus and counting. Since then, I've mainly been teaching post-16 and doing recreational maths. It's much more fun 🙂
@icecolbeveridge Are all continued fractions solvable (in the sense that one can easily determine if they converge to a value, and if so what they converge to)
@ColinTheMathmo Always happy to consider your ideas (especially if I can fit them around childcare commitments...) 🙂
@icecolbeveridge Here's one presentation of the context and initial ideas:
I have a "more traditional" web page, but I'd also be interested in your reaction to following the ideas on the diagram.
(My attention will be patchy, as, no doubt, will yours.)
@icecolbeveridge If you're interested in contributing to that discussion I can send you a magic link. That's the setup ... the actual idea comes next.
@ColinTheMathmo I've bookmarked it to read later on (there's a likelihood of being interrupted by squabbles currently, which makes concentrated thought difficult.) I suspect it's not quite in my wheelhouse, but I'm happy to look and see if I have anything intelligent to offer 🙂
@icecolbeveridge Noted ... when you can the chance, and as always, no obligation even to read it, let alone spend time.
@ColinTheMathmo (I am on much firmer ground with simple CFs, but I think @loke's question was about generalised ones.)
@loke Yeah, I'm pretty sure simple ones converge (I'm currently at the "handwavy" stage of sureness rather than "I feel like I could convince someone" -- once I give it some thought, I expect it'll drop out quite nicely.)
@icecolbeveridge @loke in general I tend to prefer the Śleszyński-Pringsheim or van Vleck theorems (cf. https://dlmf.nist.gov/1.12.v) for proving convergence, since their criteria are often easy to verify. On a terminological note, I tend to use "continued fraction" in the general sense, and use the specific term "simple continued fraction" if all the partial numerators are unity.
