So my knowledge is fundamental:

- Dynamical Systems

- Differential Calculus

- Vector Analysis
- Finite Mathematics


You left out mathematical logic and algorithmic analysis. What problems are NP Complete, for example.

I am a mathematician, so I am not sure if that counts if it's my job ...

I suppose it might be that I have made an obsession my work. If I find a problem that captures the imagination, there is nothing better in the world than thinking about it. And the feeling of really understanding something, all the pieces falling into place - I'm not sure there is anything better in the world.

Of course it can be counterproductive also when I'm really supposed to do admin / prepare for teaching / engage in social activities, but really I just want to keep thinking about some specific mathematical point that is irking me ... I still remember how, while writing my thesis, I kept coming up with new results that really ought to be included, which was nice in a way, but not that helpful when really I was supposed to be finishing ...

I have an undergraduate math major and have taken some graduate level math classes as well.

I love applied math, but I also enjoy going through rigorous proofs and understanding the foundational logic behind widely applied methods. Linear algebra tends to come up a lot in applied math. I've bought a lot of math books to read for fun, but it does takes a lot of motivation to self-teach.

I'd kind of like to understand the mathematics of differential forms as it's the rigorous generalization of how calculus works on fields of vectors or tensors in n dimensions. It's a lot of the math developed to formulate the general theory of relativity but with more mathematically consistent notation.

Heya can anybody explain to me how the Riemann Zeta function's domain is the complex set -{1} as opposed to the set (1,infinity)?

I'm a math student and it's one of my interests. That which interests me the most is the foundations of mathematics.

Wow, I can't believe people still post in this. This was one of my first few posts here at WP.

If you like programing languages and abstract mathematics, you must like lambda calculus. It's an interesting logic :)

Yes, I do find the lambda calculus interesting. I would like to learn about in more depth.

I like combinatorics ,real analysis, and calculus. I am not quite to the obession point with anything else currently.

I have a challenge for you. Can you give a closed formulate that estimates the number of transitive binary relations one can construction on a set of N objects N >= 3.

Some reasonable closed forms giving an upper bound and a lower bound (the closer the better) would hit the spot.

I love math too! :)
Especially trigonometry,combinatorics, and calculus. But its sad about, im only 16, and teacher is going to start calculus only after 2 years.
If someone else here would want to talk about physics, math,electronics, calculus just PM me :)

not sure how to get this into closed form but n choose 2 * (n choose 2)! I don't really know the binomial identites with multiplication of the factors to get a closed form that well as the number of ways to order the pairs is n choose 2 then we have to order those pairs that much.

Arithmetic and statistics. Basically I just like calculation.

Don't worry about the teacher.

Teach yourself using youtube or other sites.

There is a huge amount of learning material on the net for all levels.

Don't let your school hold you back.

:D
