Re: Fundamental Theorem of Algebra

For general metric vector spaces, only one of the implications holds (which one?). I've only worked with Euclidean spaces (I think the complex plane is one of them?) and in these, both hold, so I can't answer. Maybe after some reading :) Together with the definition of continous functions Quaanol g...

Re: Fundamental Theorem of Algebra

Are you aware that the continuous preimage of an open set is open? (This is a fundamental property of continuity, often taken as the definition.) I wasn't, but it makes complete sense. At least on the reals, I think I can even prove it. We have an f(x) from K to P (subsets of R) and P is open, so ∀...

Fundamental Theorem of Algebra

The title is a bit misleading. I've been looking at proofs of the theorem, and this one is the easiest I've come across. It's the first lemma that has me confused. Reading several versions of the proof, I've understood the following: you take a disk D on the complex plane (centered on the origin) th...

Re: A very stupid question regarding sets & Euler's function

So the three sets aren't all that intimately connected at all, we basically just say "We somehow thought of a set which has as many elements as ϕ(m)*ϕ(n) and also happens to be the set of numbers that ϕ(mn) counts."

Right? That would be good enough for me.
