On the Delta Set of a 3-generated Numerical Monoid

چکیده
Let S = 〈n1, n2, n3〉 be a numerical monoid of embedding dimension 3. We characterize the positive integers m such that m ∈ ∆(S). If n1 = 3, we show that {23 3 − 2} ⊆ ∆(S) ⊆ [1, n2+n3 3 − 2]∩N. We conclude by determining necessary and sufficient conditions on n1, n2 and n3 so that ∆(S) is a singleton.

Delta Sets of Numerical Monoids Are Eventually Periodic
Let M be a numerical monoid (i.e., an additive submonoid of N0) with minimal generating set 〈n1, . . . , nt〉. For m ∈ M , if m = Pt i=1 xini, then Pt i=1 xi is called a factorization length of m. We denote by L(m) = {m1, . . . , mk} (where mi < mi+1 for each 1 ≤ i < k) the set of all possible factorization lengths of m. The Delta set of m is defined by ∆(m) = {mi+1 −mi | 1 ≤ i < k } and the Del...
متن کاملDelta Sets of Numerical Monoids Using Non-minimal Sets of Generators
Several recent papers have studied the structure of the delta set of a numerical monoid. We continue this work with the assumption that the generating set S chosen for the numerical monoid M is not necessarily minimal. We show that for certain choices of S, the resulting delta set can be made (in terms of cardinality) arbitrarily large or small. We close with a close analysis of the case where ...

Let S be a numerical monoid with minimal generating set 〈n1, . . . , nt〉. For m ∈ S, if m = Pt i=1 xini, then Pt i=1 xi is called a factorization length of m. We denote by L(m) = {m1, . . . , mk} (where mi < mi+1 for each 1 ≤ i < k) the set of all possible factorization lengths of m. The Delta set of m is defined by ∆(m) = {mi+1 − mi | 1 ≤ i < k } and the Delta set of S by ∆(S) = ∪m∈S∆(m). In t...
متن کاملOn quasi-Armendariz skew monoid rings
Let $R$ be a unitary ring with an endomorphism $σ$ and $F∪{0}$ be the free monoid generated by $U={u_1,…,u_t}$ with $0$ added, and $M$ be a factor of $F$ setting certain monomial in $U$ to $0$, enough so that, for some natural number $n$, $M^n=0$. In this paper, we give a sufficient condition for a ring $R$ such that the skew monoid ring $R*M$ is quasi-Armendariz (By Hirano a ring $R$ is called...
متن کاملOn zero divisor graph of unique product monoid rings over Noetherian reversible ring
Let $R$ be an associative ring with identity and $Z^*(R)$ be its set of non-zero zero divisors. The zero-divisor graph of $R$, denoted by $Gamma(R)$, is the graph whose vertices are the non-zero zero-divisors of $R$, and two distinct vertices $r$ and $s$ are adjacent if and only if $rs=0$ or $sr=0$. In this paper, we bring some results about undirected zero-divisor graph of a monoid ring o...
