WebDefine S: Z + → Z + by the rule: For all integers n, S ( n) = the sum of the positive divisors of n. a. Is S one-to-one? The answer is no. Counterexample: S ( 6) = 1 + 2 + 3 = 6 and S ( 11) = 1 + 11 = 12, s o S ( 6) = S ( 11) but 6 ≠ 11. In this one I understand that I need to choose any positive integer and show that there are different ... Web(b) Prove that [a] is a nonunit in Zn if and only if [a] is a zero divisor.

WebMar 24, 2024 · A divisor, also called a factor, of a number n is a number d which divides n (written d n). For integers, only positive divisors are usually considered, though obviously the negative of any positive divisor is itself a divisor. A list of (positive) divisors of a given integer n may be returned by the Wolfram Language function Divisors[n]. Sums and … = .] Solution: Since \=" is an equivalence relation \»" is also.

WebMar 12, 2024 · 1. Let R be a finite ring. Then every non-zero element of R is either a zero-divisor or a unit, but not both. Proof: suppose that a is a zero-divisor. Then clearly, a cannot be a unit. For if a b = 1, and if we have c ≠ 0 such that c a = 0, then we would have c a b = c 1 = c = 0. This is a contradiction. Websmooth divisor which is homologous to a non-connected smooth divisor, then it has a surjective morphism to a curve with some multiple bers, and the two divisors are both unions of bers. This is our second main result, Theorem 5.1. We also give an example of two connected smooth divisors which are homolo-gous but have di erent Betti numbers.
