Since this is impossible it follows that b has no prime divisors at all. Therefore b = ±1 and f 6 Z. • As we saw 3 the Gaussian integers satisfy something quite analogous to the division algorithm of the integers, or the polynomials in one variable with coefficients from a field. Consequently it shares many properties of these commutative rings with identity, including unique prime factorization. 2 = {n + m^/—2 : n,m € Z} with the usual properties of addition and multiplication. 7 Polynomials and Other Analogues of the Integers 45 x = n + my/—2 and we define N(x) = n2 + 2m2 G Z, then N(xy) = N(x)N(y) for all x and y € R2 and n2+2m2 = ( n + m v / z 2 ) ( n - m V ^ 2 ) .

Just as we have enlarged our domain in order to solve other equations that we were interested in, we now do the same for this one. Fortunately this process will not be endless, for later we shall see that the buck stops here! We shall call a solution to this later equation i. Thus i2 = —1. Of course, we will also require that (—i)2 — — 1. 6 The Complex Numbers 33 numbers. A complex number is, by definition, anything of the form z — a + bi, where a and b are real. We refer to a and b, respectively, as the real and imaginary part of z.

Prove if if is a normal subgroup of G then G/H can be made into a group and the map TT : G —• G/H sending g h-> gH is a homomorphism whose kernel is H. 5. Suppose / : G\ —» G2 is a homomorphism.
