>they tell reimu theyre like a delicacy so they'll eat all of them
That's some excellent logic right there.

What does she teach?

Because it's not a priori clear if such a gap can be constructed, or even exists at all. In (3+1) spacetime dimensions such a gap would correspond to a gluing of two 4-manifolds (our universe and Gensokyo) along a 3-dimensional submanifold (the gap). This can be seen as a 4-corbordism between empty sets (assuming our universe as well as Gensokyo are closed and compact), which maps to a ℂ-linear endomorphism on ℂ by under a unitary topological quantum field theory (UTQFT). Since all such endomophisms correspond to multiplication by a complex number, it follows that this gluing must correspond to a multiplication by the norm induced of the vector that lies in the image Hilbert space of the 3-dimensional submanifold under the UTQFT functor. However it has been shown recently that 4-dimensional UTQFTs do not in general induce positive-definite inner products on the Hilbert spaces, due to the existence of Mazur manifolds having exotic differential structures. Yukari therefore cannot create gaps that can sustain both realities consistently across them unless she can prove that neither Gensokyo nor our universe are 4-dimensional Mazur manifolds.
Of course this isn't the only obstruction; Yukari would also have to prove non-Abelian Yang-Mills theories can be consistently constructed along the gaps as well, since otherwise matter and physical laws wouldn't behave the same across the gap. This introduces boundary conditions on the matter and gauge fields along the gaps, and the existence + uniqueness of the solutions of the resulting Euler-Lagrange equations obeying such boundary conditions must be proven as well.
Also Yukari can't just say "fuck all that shit I can use magic", since this gap has to connect to our universe where magic doesn't exist.

Koishi's a fucking idiot.

>Eirin aces the Dehn surgery part of the course
You've got a pretty twisted sense of humor.

I was at work so I didn't have the time to read your dumb shit and hand your dumbass back to you over and over again.
>But the elixir wasn't created within Gensokyo? And it was made well before it.
Granted, that still doesn't mean jack shit in terms of math.
>Because I brought up plenty of other things
Such as? Creating youkai? It was humans that created them. Here allow me to breakdown what was supposedly a simple paragraph that you apparently couldn't understand.
>according to Yukari Yakumo it was the moon's dim light which gave birth to the youkai by causing humanity to fear and create legends about them
Human created youkai with their fear. If anything this makes the creation of the barrier all the more impressive as it severs the need for youkai to depend on human emotions.
>while Kaguya Houraisan claims that youkai and magic were created by Lunarians in order to regulate the earth's "filth".
Good job leaving out "while Kaguya Houraisan claims" bit. This dumb shit was spoken right before a battle of course this is at best an exaggeration.
>She didn't do it alone, and it's only mentioned that she's "tied to the creation". It is quoted by Yuyuko that "not even Yukari could create a barrier of this level by herself."
Granted just proving the existence of something like this can be done is the main mathematical feat that I was referring to throughout this entire shitshow. Or are you going to suppose that she didn't do that alone either?
>Your whole point comes down to the fact that humans were able to create something Yukari was incapable of which only shows that she's inferior outside gensokyo.
It isn't, and the boundary made by Yukari and the humans were completely different. Conflating the primitive "just put the shit we don't want" kind of barrier that were made by humans and Yukari's "containing a literally an entire universe" kind of barrier shows how absolutely brainless you are.
>After all this you have still not disproved the fact that Eirin is more intelligent and better at math than Yukari
Need I quote Akyuu's chronicles? The proof rests on your shoulders, idiot.
>we don't rate knowledge by accomplishment No one is. Creation and even understanding the existence of something like the Hakurei barrier is in itself merely a testament.
>especially due to the fact that Eirin is highly capable of doing the same thing
Even though the fact remains that there is still no definitive canonical proof that Eirin has done anything of the sort.
>As a lunarian Eirin did not have the desire or was given a task to do such things, she's not an engineer or a youkai desperate to hide.
Yes. She's a doctor, which is a lot worse in terms of mathematics than engineers like NItori.
> I'll be off to study some TQFT and CFT
Now that's interesting. Let's see how much you know. Post even one single interesting result in TQFT and CFT (each) and I'll give you the benefit of the doubt regarding Eirin's purported intelligence.

Yukari and hag words can't be separated.
