can't think of a single practically useful univariate generating function that has bad analytic properties. By "practically useful", I mean something like "can be found printed in a paper or book". Obviously any precise definition will say almost no sequences of reals have convergent generating functions, but that's just not interesting. The multivariate case is another story, particularly with infinitely many variables, but that's not what the person was talking about.

Wait, what's that? Nor does the rest of the article really make clear what "the general linear recurrence problem" is. It talks about finding a closed-form solution given a recurrence relation, and about extracting a recurrence relation given a generating function. Is "the" general linear recurrence

Additionally, I am a bit biased towards the content in the wiki and it is hard for me to point out precise areas which might prove to be educationally ill-formed to most. So I would like some feedback in that direction, thank you! (Ex: The 'Article is a mess' post above seems rather insightful, and

Finite sequences embed into infinite sequences in a natural way, by appending all 0s. So, for example, the sequence of coefficients of the series you mention can be understood to be (0, 0, ..., 0, (2/5)^64, ..., 1/5^64, 0, 0, 0, ...). The emphasis on "infinite" in the lead is slightly misplaced.
2828:
The writing frequently feels inappropriate for an encyclopedia. It's often clearly trying to teach the reader from the ground up rather than summarize the topic, like in "Example 3: Generating functions for mutually recursive sequences". Consequently it's often long-winded with frequent asides and

Also, how about this one: We just list a couple applications of generating functions (I honestly think snake oil or something is a good enough thing to convince people that they're 'useful', and then maintain a 'main article' on applications). I wish to scrap off the entire J-fraction part, write

of the article indicates that "generating series" is "more correct" than "generating function." While I agree that generating functions aren't really functions (for instance, because their evaluation at specific points isn't what they're about), I worry that they aren't really series either (for

Very old thread, but I don't agree. A huge number of interesting generating functions are meromorphic. The main heuristic motivation for using exponential generating functions is often that the coefficients grow too quickly for an ordinary generating function to converge. Off the top of my head I

By far the biggest issue: the material on OGF's and EGF's needs to be split into its own articles. This article should be a panoramic view of generating functions with tons of links to specific instances (as is already done for Lambert, Bell, and formal Dirichlet series). The current version is

Good point about uniqueness of two-sided inverses, probably worth saying in the article. Instead of saying this is unique, say this is a two-sided inverse, and thus it is unique. (I'm not sure if two-sided inverses are unique in non-associative rings, but I think that's out-of-scope for the
2832:
There are tons of "local" issues, like the fact that none of the "precise, technical" definitions actually reference base rings or power series, the large number of lengthy equations that should be displayed rather than in-line, the ad-hoc, inconsistent use of theorem-like "environments"....
1594: 272:
The information here is really not enough... it didn't give me any idea how to calculate the generating function coefficients. It's algebra and series, but the article should list the most used tricks: binomial theorem, infinite geometric series, convolution products, etc.
2521:
The first sentence of the introduction says a generating function is "an infinite sequence of numbers". The second sentence says it is a single number, namely: "the sum of this infinite series". Apart from the morph of "sequence" into "series", this is pretty confusing.
2489: 1553:
instance, because whether or not they converge isn't what they're about). Given that there is now a citation (which I haven't checked!) to show that "generating series" is also in use, might we simply say that it is an "alternative" rather than "more correct"?

the sum; this sum is not a number because the individual summands are not numbers. I think Bill's suggestion is a completely acceptable alternative for that sentence. The immediately following sentence leaves something to be desired, as well.

Spreading the content to multiple articles that specialize in specific aspects sounds good to me. However, much of the content is quite interesting to me, so I am hoping that, as it leaves this article, it does go somewhere, not merely to the

It seems to be a complaint that the article is too huge to read. I was wondering if we can cut some sections down. Obviously there must have been those before me who wondered, so I mean to ask: What's a systematic way to maintain such a list?

I said the growth rate is "often" the main heuristic. It's certainly not the only one. I also did not say there are no "useful" univariate generating functions with bad analytic properties, though I like the examples in your paper, like

This article is fairly typical of current Knowledge (XXG) mathematics articles: it dives headlong into a mass of detail without first explaining the basics. This is supposed to be an online encyclopedia, not a maths textbook!
2593:, as I said in my edit summary when I changed it and as RobLandau said above, is certain to give some people the impression that it means “The number that this series sums to is the generating function”, which is not right. 3700:
For starters, we should probably remove P-holonomic functions and J-fractions and give them their dedicated pages. But beyond that, at the time of writing this, I am not sure of what optimisations one can perform.

Indeed, it is very, very old. But as long as it is being revived: you are wrong about both the heuristic and the substance. The "right" heuristic for exponential generating functions is about labelings, and

I noticed that all summation formulae on the page look like this: for each natural n sum a_i*x^n or something. I believe this should be fixed, because 1/(1-x) is not x+x^2+x^3+... but 1+x+x^2+x^3...
