Finite Abelian Groups as Galois Groups
... common divisor of its coefficients is 1. Now suppose h(X) ∈ Z[X] is a monic polynomial that factors as h(X) = f (X)g(X), with f (X), g(X) monic polynomials in Q[X]. Then in fact, f (X) and g(X) have integer coefficients. To see this, write f (X) = ab f0 (X) and g(X) = dc g0 (X), where, f0 (X) and g ...

In a commutative ring, chirality (handedness) is a moot point, but in noncommutative rings, ideals can be either left or right absorbing (the nonideal factor goes on the left or right, respectively) and then they ...

Solving Poly. Eq.
... then we can factor out x – 1 to get p(x) = (x – 1)(x2 + 2x + 9). At this point, the quadratic formula tells us that the other two roots of p(x) are 1 i 8 . This idea always works when we can find a root. For if r is a root of P(x) so that P(r) = 0, then we can use the division algorithm to fin ...
