For what n is R^n a division algebra?


When n is 1, 2, 4, or 8, we have the reals, complexes, quaternions, and octonions. These are the only values of n where this happens. We will see how cohomology theories can provide a way to phrase and answer this question by using something called the "Hopf invariant."
