WebDe nition 1.1. Let Rbe a ring. A divisor of zero or zero divisor in Ris an element r2R, such that there exists an s2Rwith s6= 0 and rs= 0. Thus, for example, 0 is always a zero divisor. Example: in Z=6Z, 0 = 2 3, hence both 2 and 3 are divisors of zero. One way to nd divisors of zero is as follows: De nition 1.2. Let Rbe a ring.

Web4 SOLUTION FOR SAMPLE FINALS has a solution in Zp if and only if p ≡ 1( mod 4). (Hint: use the fact that the group of units is cyclic.) Solution. If x = b is a solution, then b is an element of order 4 in Up ∼= Zp−1. Zp−1 has an element of order 4 if and only if 4 p−1. 5. Web124 Zero divisors Proof. Let a be a unit and a zero divisor in R, with multiplicative inverse b and compli-mentary zero divisor x. x = 1·x = (ba)x = b(ax) = b ·0 = 0, This is a contradiction since x must be nonzero. Exercise 1. In a commutative ring R, a nonzero divisor must be a unit. 1 Let m be a fixed integer > 1. Proposition 8.4.
