Divisions of applied mathematics

AI Thread Summary
The discussion revolves around the definition of applied mathematics as outlined by Wikipedia, highlighting various fields such as differential equations, numerical analysis, mathematical physics, and more. Participants express opinions on the inclusion of meteorology and atmospheric science, suggesting that these areas could fall under differential equations. One contributor emphasizes their focus on nonlinear differential equations, matrix theory, and bifurcation theory, while another critiques the list for mixing pure mathematics with applied fields. The conversation also touches on the relevance of various mathematical analyses in physics and industry applications, with specific interests noted in calculus of variation, differential geometry, elastic theory, and mathematical finance. Overall, the dialogue reflects a deep engagement with the intersections of mathematics and its practical applications.

Complementing the fields of physics thread, and as a bit of fun :wink:, I wondered what people make of wikipedia's definition of divisions within applied maths:

Applicable areas of mathematics include most notably

* differential equations (ODEs and PDEs)
* numerical analysis/scientific computing
* approximation theory and representation theory
* matrix theory
* mathematical physics
* mathematical methods of engineering
* nonlinear optimization
* operations research, including linear programming
* continuous modelling
* control theory
* mathematical biology
* bioinformatics
* information theory
* game theory
* probability
* mathematical economics
* financial mathematics
* actuarial science
* cryptography
* graph theory (as applied to network analysis)
* statistics
* parts of theoretical computer science

what about meteorology/ atmospheric science? Also J77, what type of applied math are you into?

That's a good one.

I think it would come under differential equations in this formulation but then so should, for example, math biology.

The base of my work would be nonlinear differential equations but of many forms... ODEs (including nonsmooth), PDEs, DDEs...

This involves matrix theory too.

And, bifurcation theory which I think should be on the list!

Actually, if you number the lsit from 1 to 22, in my research I've employed...

1, 2, 4, 5, 6, 10, 22

I'm not sure what 3 and 9 would include...

Calculus of Variation?

Elastic theory?

All kind of analysis find applications in Physics, and practical Industry.
like
Differential Geometry
Tensor Analysis
Algebraic Topology
Variation Analysis
Elastic Theory
Mathematical Dynamic of any kind.

The list looks weird to me because some of the items are maths, and some are applicable field. Personally, I would consider Differential Eqn is a branch of Maths which has a lot of applications in practical world.

PS: I am going to be focusing on Calculus of Variation, Differential Geometry, Elastic Theory, and Mathematical Finance.

TL;DR Summary: I want to do a PhD in applied math but I hate group theory, is this a big problem? Hello, I am a second-year math and physics double major with a minor in data science. I just finished group theory (today actually), and it was my least favorite class in all of university so far. It doesn't interest me, and I am also very bad at it compared to other math courses I have done. The other courses I have done are calculus I-III, ODEs, Linear Algebra, and Prob/Stats. Is it a...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation. This article's date received is 2022-11-15...
