ITT: post fields of math that have no applications outside of theoretical physics or niche occupations

[Anonymous No.10964796]

But Complex Analysis has applications in Physics and EE.

Even your bait is dumb, OP.

[Anonymous No.10964826]

>>10964811
The point is I wanted to exclude EE without including it in my OP so that people could post other fields of math.

Yes EE is not niche in the general definition of the word but its not a hugely popular or applicable field either

Is it just me, or is complex analysis taught a lot like calculus and not so much like analysis?

Take any book on analysis, they introduce you to sets, metric spaces, covers, unions, intersections, and what it means for a sequence to converge. Yet take a look at a book on complex analysis, they don't talk about those. They just mention derivatives, and contour integrals. and various functions.

>>10964963
Wtf is analysis.. I'm trying to finish my maths degree at a different school and everything requires analysis 1, looking at the syllabus it looks like basic calculus?

[Anonymous No.10965007]

THere is nothing outside EE everything is inside EE. EE is everywhere.

If it’s been studied for more than 30 years then it usually has application in nontrivial areas dipshit. People thought number theory in general had no practical value until cryptography. You cannot know a priori which math is “””””useless””””””
Hint: it’s all useful in some way, so you ought to divide the question into: do my priorities lie in applying stuff we know or in finding new mathematics?

> it looks like basic calculus?
Yes that pretty much what it should be.

But don't get fooled by it just because it looks basic. It's all about constructing the theorems, such as the ones calculus is based on, from basic principles. You are going to have to prove weather or not limits and derivatives exist based on general assumptions. Sometimes you might be asked to find the value of a series or two.

[Anonymous No.10965023]

>>10965014
Yes. There’s physics, but also robotics and the loads of computational topology problems out there. Topology has become useful for areas in TCS
>>10965007
>t. EE
I like EE and do lots of personal projects out of stuff I learn in art of electronics, but it’s not all since even as a mature field it can’t penetrate into TCS, physics, or other subjects. That is, RF and analog have given us lots of great stuff, but just because information theory started in EE doesn’t mean that EE researchers meaningfully contribute to communication complexity

If you want to go hard mode, do analytic combinatorics or analytic number theory and tell me “complex analysis is easy.”

Knot theory is used extensively in modeling protein folding. I know point-set topology is used in statistics. By definition topology is the study of space, so I'm assuming physics uses it.

nanocomposite research suggests otherwise. it gets deep into chemistry, physics, and material science.

Try taking several complex variables course, it will be nothing like calculus

Reminder you don't really need 'complex analysis' for control theory, signal processing and circuits. Highschool level complex numbers with a few extra things is all you need.
