Mmh... lets see. My algebra-prof says group theory has plenty of applications. So it could be anything...
Maybe Forestry?

>>7136550

>>7136592
The eyes are spread too far apart, and the nose is too narrow, for him to be black.

>>7136588
If people care I'll post what it is. You could google LFT and complexes and probably get the answer. But yeah, it is an application of group theory

>>7136588
Well, he also said LFT, which I assume stands for linear fractional transformation. So the line of reasoning would go:

LFT + group theory > modular group > complex analysis > complex functions > branch points >branches > trees > forestry

>>7136600
>>7136588
LFT= ligand field theory

Complexes are metal complexes

group theory is used to study it.

What I do can be described as the union of coordination chemistry and quantum chemistry.

Ohh, I totally thought you meant linear fractional transformations, which are elements in the modular group. Then I just assumed complexes could be interpreted as CW or simplicial complexes, and I figured you studied cohomology on Riemann manifolds or something.

Oh, cool. So internal logics/languagesm categorical semantics?

>>7136805
Good. Even more precisely, homotopy type theory

>>7136809
Yeah, very exciting stuff! I'm studying category theory with more focus on higher topo(i/oses), as well as a scheme-flavored approach to elliptic curves and number theory.

>>7136732
wat, Herbrand 80 years ago? :D

>equalities are paths
I tried for some time to understand the semantics for equality a presented in
http://ncatlab.org/nlab/show/univalence+axiom

Am I on the right track with this?:
You have the diagonal map "<span class="math">\Delta_A:A\to (A \times A) :: a \mapsto (a,a)[/spoiler]".
The image of <span class="math">\Delta_A[/spoiler] represents the equality relation.
Now if <span class="math">p:A^I[/spoiler] is a path in <span class="math">A[/spoiler] and if <span class="math">ends(p):=(p_0,p_1)[/spoiler] maps it to its endpoints, then any map <span class="math">aloop:A\to A^I[/spoiler] which maps <span class="math">A[/spoiler] to some loop provides a factorization of <span class="math">\delta=ends\circ aloop[/spoiler].
Now, roughly, if <span class="math">end[/spoiler] is invertible, we can replace the substitute relation with the path object.
(What's not mentioned above, I guess, is that all of this must be done for types <span class="math">a:A\vdash Q(a): Type [/spoiler]. Only then, i.e. if there is more structure going on, can the above "inversion" be nontrivial.)

Also, more generally, can you connect the dots for me how the dependent product function - defined as adjoint to the base change in the -slice- categories gives rise to the normal dependent product, which clearly is defined a a map of objects, not just bundle/display maps.

>>7136812
Nice! HoTT is pretty much infinity-toposes everywhere when you look at the semantics side.

>>7136820
I wasn't there to cry when Herbrand died, i was thinking about Grothendieck ;)

>>7136826
Ah, well I think he wasn't literally in the mountains, just in some village close to the mountains.
Herbrand, though, he died a mans death.

Pic related are the diagrams I refer to.
Let it be noted that I don't understand the buzzword "homotopy lifting property", which may be needed here.

Because gossip is always fun,
form this post from the weekend, and some of the links it points to, I read out that some of the (old) topos people "seem to be a little pissed/frustrated" that the shit only now takes off when their carriers end
