>My only quip is that the particular terms "injectivity" "surjectivity" etc. aren't usually taught (in my experience)
fair enough, I don't think I heard the words until going to university

meanwhile there's russian high schools where the students are already learning about manifolds and algebra :/

well i can assure you that wont happen

maybe you can pray to the climate gods that global warming will come kill me :)

It's pretty easy to come up with at least ~50 mathematicians more influential than Wiles

Not knocking his achievements but he's just too modern to have affected that much yet

It's true for certain nice rings

Needless to say no one in the class came up with the counter example ring (from Hungerford's algebra book) of infinite matrices with finitely many non-zero elements in each column, which satisfies [math] R\cong R^2 [/math].

i did summer research projects after my 2nd and 3rd years of undergrad

Still looking for an answer to this:

If C and D are matrices with integer entries satisfying C(D^T) = D(C^T), why is det(iC+D) non-zero?

i think we should be more concerned about teaching before we both worrying about evaluation

let C,D be two matrices with integer entries satisfying (C^T)D=(D^T)c (T meaning transpose)

why must we have det(iC+D) non-zero?

it's obviously because they don't know any higher math

brats need to show off with something
