Jan10 awarded Yearling May24 comment Math blogs, pros and cons for writers? this question has been on my mind too, what blogs do you keep up with? May12 awarded Enthusiast Apr8 comment What are the generators of $(\mathbb{R},+)$? well you'll certainly never find a minimal set of generators, for instance .1+.1+.1+.1+.1+.1+.1+.1+.1+.1 = 1. Mar30 awarded Nice Question Mar25 asked H0w have group theory and fractal geometry been combined? Mar6 comment If a collection of sets is a subbase for a topology $\tau_0$ and a base for a topology $\tau_1$, can we conclude $\tau_0 = \tau_1$? the intersection of open balls can be described as the union of different open balls Mar5 accepted Alternating Series Using Other Roots of Unity Mar5 comment Alternating Series Using Other Roots of Unity This is perfect thanks! Mar5 awarded Commentator Mar5 comment Alternating Series Using Other Roots of Unity I guess I'm not sold on my last part, if a series converges when it contains a primitive p-th root of unity, will it converge for any primitive q-th root of unity where q>p? Mar5 asked Alternating Series Using Other Roots of Unity Mar5 awarded Critic Mar5 comment Show that all abelian groups of order 21 and 35 are cyclic. Do you know FTFGAG? Jan27 awarded Supporter Jan12 comment A field that is an ordered field in two distinct ways Remember that we only care that P is a subset, closed under addition & multiplication, and for any x $\in$ F, $x\in P$ or $-x\in P$ so the ordered field is not worried about additive inverses. Note: I think you're on the right track with automorphisms. I think that these subsets show some consequences of defining automorphisms on a field extension, having these two distinct automorphisms of F is a base step for Galois theory which is monumental in math and helps with proving that there is no general solution by radicals of polynomials with degree greater than 4 Jan12 answered Gaussian Integers Question Jan12 comment Gaussian Integers Question your link isn't working correctly for me. What is F?
