Let $R$ be a commutative ring and $I$ an ideal of $R$. The zero-divisor graph of $R$ with respect to $I$, denoted by $Gamma_I(R)$, is the simple graph whose vertex set is ${x in Rsetminus I mid xy in I$, for some $y in Rsetminus I}$, with two distinct vertices $x$ and $y$ are adjacent if and only if $xy in I$. In this paper, we state a relation between zero-divisor graph of $R$ with respec...

Finite affine groups are given by groups of translations and di- lations on finite cyclic groups. For cyclic groups of prime order we develop a time-scale (wavelet) analysis and show that for a large class of non-zero window signals/vectors, the generated full cyclic wavelet system constitutes a frame whose canonical dual is a cyclic wavelet frame.

We present a derivation of the numerical phenomenon that differences between Riemann zeta function's nontrivial zeros tend to avoid being equal imaginary parts themselves, property called statistical "repulsion" and their differences. Our relies on properties prime function, whose singularity structure specifies positions zeros. show function critical line is asymptotically normally distributed...

we call a module  essentially retractable if homr for all essential submodules n of m. for a right fbn ring r, it is shown that: (i)  a non-zero module  is retractable (in the sense that homr for all non-zero ) if and only if certain factor modules of m are essentially retractable nonsingular modules over r modulo their annihilators. (ii)  a non-zero module  is essentially retractable if and on...

We prove the generalized Hyers--Ulam stability  of $n$-th order linear differential equation of the form $$y^{(n)}+p_{1}(x)y^{(n-1)}+ cdots+p_{n-1}(x)y^{prime}+p_{n}(x)y=f(x),$$ with condition that there exists a non--zero solution of corresponding homogeneous equation. Our main results extend and improve the corresponding results obtained by many authors.

It is known that A-paths of length 0 mod m satisfy the Erd?s-Pósa property if m=2 or m=4, but not m>4 composite. We show p prime, then property. More generally, in framework undirected group-labeled graphs, we characterize abelian groups ? and elements ??? for which holds weight ?.

The set $\mathbb{Z}_p[x]$ consists of all polynomials with coefficients in the field $\mathbb{Z}_p$, where $p$ is prime. If a polynomial $f(x)$ irreducible over $\mathbb{Z}_p$ then $\frac{\mathbb{Z}_p[x] }{ \langle f(x) \rangle}$ field. reducible polynomial, every non-zero element }{\langle either zero-divisor or unit. we exclude zero-divisors and zero, have finite Abelian group under multiplic...
