Q: Real Analysis question from my homework #5

Sammy CowgillFor a set E ⊂ R, let E∗ = {(x, y) ∈ R^2 : x − y ∈ E}. Let A be the collection of sets E such that E ∗ is m2-measurable. Show that A is a σ-algebra.

@amWhy but do the meta-chatrooms require meta-meta-chatrooms?
 
@XanderHenderson No there's a multi-chatroom META-meta-chat-room to over-seen by the secret Supreme Meta-of-all-metas.
 
@amWhy Off-topic conspiracies within off-topic conspiracies! (this message has been moved to trash)
 
@XanderHenderson heh

Check out this charmer math.stackexchange.com/q/3618544/29335 . “I want answer” “ Thanks a lot for editing but not giving the answer. ” “when I will get my answer” “ I want a proper answer.This doubt is literally eating me up for days ” Suspiciously contrived rudeness.
 
@rschwieb Agreed!
@rschwieb There was a similarly contrived question an hour ago about rectangles.

Wow... I just received a friendly comment below another's answer, thanking me for editing their post! (Not much of an edit, but not trivial either.) It makes me realize how often such work goes unnoticed. Sort of made my day! :-)

The body of this post just seems too deliberately baited: https://math.stackexchange.com/q/3618318/29335

Do we have a bad actor manufacturing accounts to sow this junk?

@rschwieb Yikes. My guess is we have someone, probably who had to drop out of classes, who has nothing better to do under current circumstances, than troll this site, and probably many more like it.
@amWhy Same frequent LHFG, frequent flyer answered this, now closed question.
 
4:34 PM
Ditto: Poor question, one particularly poor answer. math.stackexchange.com/questions/3618906/…
Another poor question in need of closure, answered by a FGITW, LHFG answerer. math.stackexchange.com/questions/3617874/…

@amWhy sorry, I seemed to have repeated an earlier link, when I meant to post a new link. :( ::facepalm::)
 
5:03 PM
@XanderHenderson What about $\ddot \smile$? :P

D1, D2, D3.
D4, D5, D6.
D7, D8, D9.
C1, C2, C3.
C4, C5, C6.
C7, C8, C9.
Reopen? It shows effort and has nothing to do with the claimed duplicate.
@amWhy Closed.

This asker has flooded the site with four vlq questions in two hours. First: math.stackexchange.com/q/3619079/9003
 
7:34 PM
@user21820 this has been reopened.
@amWhy Sigh...
 
@XanderHenderson Yes, times $4$. I'm suspecting by now, they may be blocked from asking. Small consolations, until they appear on meta, ranting about "Why can't I post any questions?!?!.
