8 The Gelfond-Schneider Theorem and Some Related Results
... the transcendence of eπ also follows from this result. We note that the following are equivalent forms of this result: (i) If ` and β are complex numbers with ` 6= 0 and β 6∈ Q, then at least one of the three numbers e` , β, and eβ` is transcendental. (ii) If α and β are non-zero algebraic numbers w ...

... Intuitively we all know what the dimension of something is supposed to be. A point is 0-dimensional, a line 1-dimesional, a plane 2-dimensional, the space we live in 3-dimensional. The dimension gives the number of free parameters, the number of coordinates needed to specify a point. Also a curved l ...

... A division ring satisfies all requirements of a field except that multiplication is not commutative. Claim 1 : When V is a cylic left R- module, then HomR (V, V ), is a division ring. ( Aside: The proof does not use the commutativity of R, so we work with a general ring R in what follows. However, t ...

... exists b ∈ Zp such that f (b) = b2 − a ≡ 0 mod p. So if a = a0 + a1 p + a2 p2 + ... and b = b0 + b1 p + b2 p2 + ... then b2 ≡ a mod p iff. b20 ≡ a0 mod p. Thus, we really just need to check if there exists an integer b0 with 0 ≤ b0 < p such b20 ≡ a0 mod p. This makes the problem much simpler. The ot ...
