Z-polynomials and Ring Commutativity
We characterise polynomials f with integer coefficients such that a ring with unity R is necessarily commutative if f(x) is central for all x ∈ R. We also solve the corresponding problem without the assumption that the ring has a unity.
متن کاملCommutativity degree of $mathbb{Z}_p$≀$mathbb{Z}_{p^n}
For a nite group G the commutativity degree denote by d(G) and dend:$$d(G) =frac{|{(x; y)|x, yin G,xy = yx}|}{|G|^2}.$$ In [2] authors found commutativity degree for some groups,in this paper we nd commutativity degree for a class of groups that have high nilpontencies.
متن کاملThe Ring of Polynomials
Let D be a non empty set, let i be a natural number, and let p be a finite sequence of elements of D. Then p i is a finite sequence of elements of D. Let D be a non empty set and let a, b be elements of D. Then 〈a,b〉 is an element of D2. Let D be a non empty set, let k, n be natural numbers, let p be an element of Dk, and let q be an element of Dn. Then pa q is an element of Dk+n. Let D be a no...
متن کاملFactorization of Quadratic Polynomials in the Ring of Formal Power Series over Z
We establish necessary and sufficient conditions for a quadratic polynomial to be irre-ducible in the ring Z[[x]] of formal power series over the integers. In particular, for polynomials of the form p n + p m βx + αx 2 with n, m ≥ 1 and p prime, we show that reducibility in Z[[x]] is equivalent to reducibility in Zp[x], the ring of polynomials over the p-adic integers.
متن کاملThe Iteration Digraphs of Lambert Map Over the Local Ring $mathbb{Z}/p^kmathbb{Z}$ : Structures and Enumerations
Let $p$ be prime and $alpha:x mapsto xg^x$, the Discrete Lambert Map. For $kgeq 1,$ let $ V = {0, 1, 2, . . . , p^k-1}$. The iteration digraph is a directed graph with $V$ as the vertex set and there is a unique directed edge from $u$ to $alpha(u)$ for each $uin V.$ We denote this digraph by $G(g, p^{k}),$ where $gin (mathbb{Z}/p^kmathbb{Z})^*.$ In this piece of work, we investigate the struct...
