WEBAug 22, 2024 · A nonzero element x of a ring for which x·y=0, where y is some other nonzero element and the multiplication x·y is the multiplication of the ring. A ring with no zero divisors is known as an integral domain. Let A denote an R-algebra, so that A is a vector space over R and A×A->A (1) (x,y)|->x·y.
Why is $0$ a zero divisor? - Mathematics Stack Exchange
WEBMay 4, 2018 · The essential notion behind all 'zero divisor' terms seems to be this, R ring: It's trivial that each element x of R left-divides 0 in the sense that 0=xy for y=0, but it's much less trivial that there's an element y≠0.

WEBIf F is a zero-divisor then rF = 0 for some nonzero r ∈ R [therefore if some coef of F is not a zero-divisor then also F is not a zero divisor, so F is cancellable, by FG = FH ⇒ F(G − H) = 0 ⇒ G − H = 0].
Zero divisor - Art of Problem Solving
WEBZero divisor. In a ring , a nonzero element is said to be a zero divisor if there exists a nonzero such that . For example, in the ring of integers taken modulo 6, 2 is a zero divisor because . However, 5 is not a zero divisor mod 6 because the only solution to the equation is . 1 is not a zero divisor in any ring.
