Advanced Mathematics for Computer Science

On top of what everyone said, without a doubt take a graduate course in Neural Networks.

Why?

At a minimum IMO:
Discrete math covers such a potporrui of stuff you will see in CS that any decent CS program will require it.
More Statistics than covered in Discrete.
Linear Algebra for graphics and matrix work you will see popup
and
if you can
2nd course in logic preferablly covering HOL(higher order logic) you will see if you ever mess with Lisp, Haskell, and theorem proving.
Abstract algebra if you plan on doing any crypto stuff since a lot of advance number theory is used.
Public key cryptography draws on many areas of mathematics, including number theory, abstract algebra, probability, and information theory.
numerical analysis if you plan on doing any scientific programming or otherwise work with very large or small numbers, etc where results have to be very precise.

Actually, chaos theory comes into play in numerical analysis:
In numerical analysis, the Newton-Raphson method of approximating the roots of a function can lead to chaotic iterations if the function has no real roots

bottom line is that you can never take/have enough mathematics as someone once said I'm sure biggrin.png

thats why im majoring in math, I just want to be sure i dont take useless courses wink.png
The three most useful math classes:

1. Linear Algebra
2. Ordinary Differential Equations
3. Convex Optimization

...and they work best if taken in that order.
In addition to what has been mentioned:
- computational geometry (a must!)
- differential geometry
- topology (primarily because it improves your understanding of the math you already know)
- signal processing
Let's see, what math classes are left? You guys haven't mentioned Algebraic Geometry, Algebraic Topology and Complex Analysis. Oh, but he needs Algebraic Geometry to learn how to manipulate polynomial expressions using Gröbner bases, and Algebraic Topology is important if you want to really understand global features of Differential Geometry, and Complex Analysis is essential for signal processing.

[/sarcasm]

Computer Scientists should learn Differential Geometry? Really? Why? If you are a physicist, sure... but for CS?

Of course, the more Math you learn, the easier it will be for you to think mathematically, and that can be very useful for a computer scientist, but I don't think every CS student should get a Ph.D. in Math to do his job.
@Alvaro: I have found all of these useful in my career - some of them don't often have specific application (like I said for topology), but really help one internalize the concepts taught at the less abstract level. The OP wanted "upper division math" - there aren't a ton of things there that are directly and obviously applicable.

I am comIng at this from the perspective of a graphics/computational-geometry phd with an undergrad math major. I don't think that this math is something that everyone would benefit from directly, but i definitely believe that it would be beneficial for anyone who works in computer graphics at a reasonably sophisticated level - not necessaily because they will use it every day, but because it helps to see the bigger picture (except computational geomety - that you really may use every day :-) ).
I second discrete mathematics, and linear algebra as a background for computer science. However I'm an applied mathematics grad student who also programs, not a true "computer scientist", so take it with a grain of salt..

These subjects can be taught at a low or high level in a class, but the subjects themselves run quite deep. Linear algebra becomes functional analysis, operator algebras, etc - fields of current research. Discrete math branches into combinatorics, graph theory, etc. You don't have to look far in discrete mathematics to stumble on unsolved problems.
I'm thinking Abstract algebra, Number theory, Graph Theory, Optimization might be the best bets. I already have to take linear algebra, and discrete math I have taken already.
If you're interested in abstract Algebra, you might want to check out the harvard video lectures by Benedict Gross; they're really good:

For (convex) optimization, there are two great video lecture series by Steven Boyd at stanford:
http://academicearth...-optimization-i
http://academicearth...optimization-ii

For numerical analysis and more advanced numerical linear algebra, I really liked Gilbert Strang's (MIT) computational engineering videos,
http://academicearth...d-engineering-i
http://academicearth...or-engineers-ii

For a lot of the topics mentioned (topology, differential geometry, nonlinear dynamics, etc), basically anything where there is a continuum instead of just finite structures, it will be difficult to make much progress without a solid grounding in real analysis. There's a great set of video lectures by Francis Su from Harvey Mudd where I did my undergrad,
