I like basic and general areas of mathematics; namely pure mathematics. Their's four big areas; algebra, analysis, geometry, and topology; number theory and arithmetic is scattered all elsewhere. So it's better to pin point your interests in four areas of mathematics instead of one.

Anyways its...

> Algebra
Abstract Algebra

> Analysis
Real Analysis

> Geometry
Differential Geometry

> Topology
Functional Analysis?

>>7784433
>With [math]A, B, C[/math] not all zero.
A true algebraist would just write
>With [math]ABC\neq 0[/math].
>>
>>7784700
A true >90IQ would know that A,B,C not all zero actually translates to A^2 + B^2 + C^2 > 0, because A or B or C could actually be 0.
>>
>>7784689
Functional analysis was where it all came together for me, felt like a pretty seamless blending of LA, analysis and topology.

y'' is an old way of expressing
[math]\frac{d^2 y}{dx^2}[/math]
so let u = y'' and the equation becomes
[math]\frac{d^3}{dx^3} \left ( \frac{1}{u^{2/3}} \right )=0[/math]
>>
I probably like algebra the most, but I have been very impressed by the power of probability.
I think it has a stigma attached to it causing people with a "pure" bend (which sounds kinda stupid to begin with) to dismiss it as a nonrigorous or purely applied field whereas it yields without much effort some powerful theoretical results (for example, I remember a very elegant proof of the Radon-Nikodym theorem for the Lebesgue measure using a martingale convergence argument)

Combinatorialist here. That's stupid. I borrow heavily from computer science, especially data structures and algorithms, in my work.

It's true you barely cover the basics in a discrete math course, but why be so divisive?

toplelogy is definitely one of the pillars of math. you will use results of it in some form in nearly every graduate level pure maths class. we used it in model theory (logic), it's used a lot in homotopy, algebraic geometry (and also in both of their connections to number theory), not to mention some complex analysis, and the theory of manifolds as a whole.
