daily reminder most 'mathfags' here haven't completed anything in cohomology

[Anonymous No.7303383]

Keep this in mind as you get advice on this board or hear from a math elitist troll. Most mathfags here are unsophisticated and between the ages of 17-19 years old. They are babies & don't practice real math yet.

You are getting advice from babies taking calculus 1-3, real analysis and abstract algebra for the very first time.

What does it even mean to "complete anything in cohomology"?

I know the definition of cohomology and I've seen a few examples. And most importantly I figured out that it doesn't interest me. There are sufficiently many other math topics which I find more interesting and which don't involve cohomologies.

Could it possibly be that OP's criticism applies to himself the most? That maybe he is an undergraduate babby who took a glimpse at an introductory algebraic toplelogy course and now believes himself to be superior to 99% o /sci/?

I think the point is this board has low level math content and the math that is discussed falls in the category of introductory mathematics (e.g. calculus 2, linear algebra, differential equations). Rarely do you see any discussions with any mathematical meat to them. Also, looking around you can easily see that most people here are freshman or sophomores.

I’ll have you know I graduated top of my class in mathematics, and I’ve been involved in numerous secret papers on triple quasi-integral semi-simple coelliptic cohomology, and I have over 300 confirmed citations. I am trained in galois cohomology and I’m the top algebraist among all US math departments.

He was perhaps the greatest mathematician in history. His contributions are so deep and far-reaching that it honestly makes me incredibly relieved to know that he was able to make his contributions in his lifetime; where would we be without him?

There are many mathematicians that are the laborers of the field; they reap the seeds that the great innovators like Galois, Hilbert, Noether, Poincaré, Lawvere, Grothendieck, Riemann, Euler, et alii, have planted. They prove smaller results, shallower results, and solve plenty of the tough problems, but the innovators have had the real influence on the progress of mathematics. All of my respect goes to them.

Daily reminder that you will be unemployed forever or earning slightly above a minimum if you know what cohomology even is. Applied mathematics is where it is at. Pure mathematics is as useless as an art degree.

Same can be said about Godel, Turing, Church, Cantor, Ramanujan, Gauss, Kolmogorov, von Neumann, etc. They are the architects, the creators, the ones that create paradigm shifts, the movers. Everyone after them just fill in small gaps here and there that are ultimately insignificant compared to the body of work their founders have done. I'd just be happy if I could fill in some small gap they left behind.

If you think Ranamujan belongs in any such list, you are literally spouting meme pop-math, and probably have no idea what his life's work consisted of. He had breathtaking grasp of various elementary number theoretic ideas and approximations by infinite series, etc...clearly a natural genius...but contributed little to theory and apparently had trouble learning complex analysis from Hardy. He did nothing even remotely close to a "paradigm" shift, not even to close to the work first rate mathematicians which are not well known by pop math enthusiasts, such as Emil Artin or Andre Weil.

Starting with an abelianized copy of the fundamental group there is an infinite exact sequence of free abelian groups teminating with your abelianized copy of the fundamental group the quotient groups of successive elements of which are very useful to think about. There are also more direct definitions of the homology groups. That things are abelian makes them a lot easier to work with and think about than the higher order homotopy groups for example. If you want something to make you shiver look up what the higher order homotopy groups for the frigging n-sphere are like. That setup with the exact sequences shows up in all kinds of subfields of math and is generally called homology. In cohomology you replace the abelian free groups with associated groups of homomorphisms and then have an exact sequence going in the opposite direction. I don't know the details yet but I'll probably have to figure it out sooner orlater.

It's an okay degree, but most well paying jobs require applied forms of education because it's easier to transition it into real world jobs.

Literally what.
Not the same guy you're responding to, but as a master's student, my interests are largely in analysis and number theory.
I liked algebraic structures and topology before I took grad level courses in them. Now I'm kind of sick of them.

Cohomology does show up in differential geometry a bit and in algebraic number theory it is of course is going to be a thing. For a differential geometric algebraic time look up De Rham cohomology.

The most intuitive way to first learn cohomology is in a basic smooth manifolds course, where you will learn about the extremely natural idea of de Rham cohomology and the Mayer-Vitoris sequence. The important parts of these concepts I think really help one better appreciate a more abstract study.

It's not about whether you're sick of something or not. Can you legitimately say cohomomlogy is not an interesting concept? "I'm not interested in cohomology" doesn't even seem like a real statement to me. And I work in pure analysis/PDEs--doesn't stop me from realizing areas I don't work on are interesting. It's not like cohomology is some sort of obscure, research level topic. It's a fundamental cornerstone of modern mathematics. I don't see how any mathematician can call anything so fundamental uninteresting.

we're not sure. Sorry to say this, but even if half the themes of modern research have something to do with cohomology, it might prove totally useless in 20 years. And in 50 years people will just be like, "it was a surely a thing, but now it's just lame and boring".
