Maybe, maybe not. I just added a comment so people won't be following the link to nowhere. But the fact that such a thing was once proposed contains information.
I won't edit it, as it needlessly bumps the question, and your comment contains all the information I would add.
I've been reading Meta.SE more since the Bash started, and now those new profiles are really starting to grate. I hope they don't intend to take them network-wide.
My plan: as soon as the new design rolls out, I write an extension to make my browser open the Activity tab (whatever it will be) by default. So I'll never even see the new vanity page.
I'm still wondering what this question was trying to ask. He can't be asking about square-integrable functions, because there aren't good measures on infinite-dimensional Hilbert spaces, so I guess $L^1(H)$ means "the space of sequences $(x_i) \subest H$ whose sequence of partial sums converge", which does not seem like a very natural space.
(Nor do I understand how $x_i \otimes y_i$ is in it, or what that should mean.)
Update: as of two minutes ago Martin Aregami gave a dictionary. Whoops.
The question desired is obvious ("How do I show this?"); the lack of clarity for me was knowing what was meant by the symbols.
Whether it should remain open in general is unrelated, but once the definitions are inserted, I do not think it's unclear what he's asking. Maybe one could throw in a word or two and a question mark while they're at it.
I was a bit worried that would be an Atwood answer. I don't entirely disagree (which is why I did not vote to reopen). But if people are going to subject themselves to a question it might as well be readable.
I was given a snippet and can't seem to parse it myself, what's the name of this format and is there a tool that will render it like latex or mathML like this site does?
Sum_{n,k} T(n,k) x^2/n! y^k = 1+ln(Sum((4+y)^binomial(n, 2)*x^n/n!, n=0..infinity))
Could I interest someone in solving a definite integral involving legendre polynomials ? Specifically I need to solve $\int_{-1}^1 x^p (1-x^2)^{\frac{d-3}{2}} P_n^d(x) dx$
Sorry, how do I format latex so that it shows up nicely ?
In case someone is interested in why the above integral is important, it basically arises when you are trying to compute the feature map of the $(x \dot y)^p$ which is a dot product kernel. Once you know the feature map you can approximate it and perhaps use multipole type approximation for fast test time performance. So basically it can be used for summing up n numbers in < O(n) time
This reminds me: I was recently reading about the Stieltjes integral in Rudin, but it came with no nice geometric interpretation or even much motivation. Why do we care about it?
Some people will go for closing as a dupe, which is not wrong. But I prefer closing for whatever reason the first one was closed. So that it's more roomba-able.
The unintentional duplicates are considered to be mostly harmless, and occasionally useful. As signposts for users who search using the words not present in the original, but present in the duplicate.
Intentional double posts, which are invariably worthless to begin with, do not carry this benefit.
Roomba = informal name of auto-deletion scripts. If you read the description, you saw that duplicates are excluded from the closed question deletion criteria.
@HatMan I personally know a mathematician with the last name Reimann. But the questions are not about his work. Yes, the spelling is wrong.
I read somewhere that the first 7 users to guess the logic of a secret hat get Eureka. The existence of the Meta.SE thread, where all the secrets spill out, threw a monkey wrench into the process. I don't think such a thread existed last year.
@HatMan Someone from SE ran a search over chat transcripts, network wide, looking for the names of the secret hats. Picked the early messages that contained an explanation of those hats. Gave Eureka to those users.
Here is an argument using open covers.
For each $x \in K$ we can find some open ball $B_x$ of positive radius, centered at $x$ and contained in $U$. Let $C_x$ be the open ball centered at $x$ with half the radius of $B_x$. Then $\{C_x : x \in K\}$ is an open cover of $K$, so there is a finite su...
@Venus: Okay. Woke up rather early, been tidying my flat so far because I have friends coming over tomorrow evening. I'll have to go to my school at lunchtime to copy a lot of old exams. How about you?
@MartinSleziak I wanna ask something. How is the number of stats profile views in our profile counted? Is it counted by the number of users here view our profile or the number of our profile has been seen?
@Venus I guess yes ! I visit robjohn's and DanielFischer's profile a lot of time everyday (digging for answers :P) .. apparently refreshing or clicking on the tabs (answers,reputation, etc) the page while I'm on it does not increase the profile view count !
This is related to the 'number of times your profile is visited by others'.
How exactly does it work? For example, in my profile page, profile view count is 171.
well i have posted some more or less lhf-level answers and a big carefully written nontrivial survey-type answer. the former gets 5-7 upvotes while the latter only got 2.
There has been a lot of inquiry about recent events. This post is meant to clear that up and avoid speculation. In particular, I am posting this as a follow-up to a comment I had made previously.
This is also a logical follow-up content in the following:
Goodbye, Bill D.

@Integrator Because they judge that the site would be better off with that question removed. Many people believe that having too many bad questions around invites further bad questions.
@Integrator They must be included in the judgment. A correct but trivial answer - say the correct evaluation of a bog-standard integral - is in many (including me) people's view not valuable enough to keep a really bad question. Something that makes the answer more than trivial, a good explanation, a neat unusual way to compute something, for example, is worth keeping.
@Integrator Good. We need more users at least looking at that. And by your efforts so far, you could also save a few by editing them into shape, you're good at that.
@N3buchadnezzar Indeed. One mitigating circumstance could be that searching for the duplicate is not so easy. But it's not that difficult that all the duplicates need to be re-answered.
You could do what professor Shifrin does when a student asks a bad question in his class and that is he edits the question into a good question that he can answer :P
@Integrator Sure. After a while, I think it would even be good to change hint answers to more complete answers (not necessarily totally complete, leaving a few standard steps to the reader is usually fine, as long as the road is clearly laid out), but one does not always remember.
@r9m Provide me an easy question that fit for this site. I'll post that question and then you give an answer to that question but your answer must be very simple that doesn't make users here amazed
@Venus hmm .. I thought of that (I was actually planning to ask my roomie to do me that favor .. but he'd die before he accepts my answer =P .. he never votes my answers for the same reason) .. in the end I couldn't come up with any question that fits the profile :-(
@N3buchadnezzar About the $\frac{te^{-t}}{(x+t^2)^2}$ integral? Not immediately. And I'm going away for a while now, so I don't have time to look into it at the moment.
I've been meaning to get into more anime a lot recently. Any other suggestions besides the obvious? (i.e. Naruto, One Piece, Bleach, DBZ, Cowboy Bebop, Yu Yu Hakusho, etc.)
FMA is my shiz. Death Note and Code Geass I should look into.
Is there something about Gurren Lagann that I just don't get, or is it really just as batshit insane as it seems to be? Every time I try to pick it up, it just tries its hardest to make absolutely no sense.
I misinterpreted what you meant. But totally. He did the exact same crap in Buu saga--he could have totally creamed fat Buu when he was SSJ3 but chose not to because he wanted Gohan, Goten, and Trunks to save the world, not him.
