The class of $n$-ary polygroups is a certain subclass of $n$-ary hypergroups, a generalization of D{"o}rnte $n$-arygroups and a generalization of polygroups. The$beta^*$-relation and the $gamma^*$-relation are the smallestequivalence relations on an $n$-ary polygroup $P$ such that$P/beta^*$ and $P/gamma^*$ are an $n$-ary group and acommutative $n$-ary group, respectively. We use the $beta^*$-...
Let $R$ be commutative ring with identity and $M$ be an $R$-module. The zero divisor graph of $M$ is denoted $Gamma{(M)}$. In this study, we are going to generalize the zero divisor graph $Gamma(M)$ to submodule-based zero divisor graph $Gamma(M, N)$ by replacing elements whose product is zero with elements whose product is in some submodules $N$ of $M$. The main objective of this pa...
The non-commuting graph $Gamma(G)$ of a non-abelian group $G$ with the center $Z(G)$ is a graph with thevertex set $V(Gamma(G))=Gsetminus Z(G)$ and two distinct vertices $x$ and $y$ are adjacent in $Gamma(G)$if and only if $xy neq yx$. The aim of this paper is to compute the spectra of some well-known NC-graphs.
Let ( L , Γ ) $(\mathfrak {L},\Gamma )$ be an isometric boundary pair associated with a closed symmetric linear relation T in Krein space H $\mathfrak {H}$ . M $M_\Gamma$ the Weyl family corresponding to We cope two main topics. First, since need not (generalized) Nevanlinna, characterization of closure and adjoint z $M_\Gamma (z)$ for some ∈ C ∖ R $z\in \mathbb {C}\setminus {R}$ becomes nontri...
for any lacunary sequence $theta = (k_{r})$, we define the concepts of $s_{theta}-$limit point and $s_{theta}-$cluster point of a sequence of fuzzy numbers $x = (x_{k})$. we introduce the new sets $lambda^{f}_{s_{theta}}(x)$, $gamma^{f}_{s_{theta}}(x)$ and prove some inclusion relaions between these and the sets $lambda^{f}_{s}(x)$, $gamma^{f}_{s}(x)$ introduced in ~cite{ayt:slpsfn} by aytar [...
Genetic diversity in strawberry is low due to its asexual propagation. One method of increasing genetic diversity, as an important tool in plant breeding, is the use of gamma rays to induce mutation. In order to determine the appropriate dosage of gamma irradiation for genetic diversity creation by mutation in strawberry, Kurdistan cultivar, and to study the influence of various doses of gamma ...
The 252Cf brachytherapy source is a spontaneous fission decay source, which is used as a neutron-emitting source. In addition to neutrons emitted from this source, gamma rays are also emitted with the average energy of 1 MeV. In this study, using the Monte Carlo N-Particle code (MCNPX), the absorbed dose rates of the neutrons, the primary gamma and the secondary gamma that generated by thermal ...
Decay rates of the positronium molecule $\text{Ps}_{2}$ into two photons and an electron-positron pair are determined. Previous studies find that these very different, \[ \Gamma\left(\text{Ps}_{2}\to e^{+}e^{-}\right)/\Gamma\left(\text{Ps}_{2}\to\gamma\gamma\right)\simeq250\text{ (previous studies)}. \] This is puzzling since both processes have body final states same order in fine structure co...
let $r$ be a commutative ring and $m$ be an $r$-module with $t(m)$ as subset, the set of torsion elements. the total graph of the module denoted by $t(gamma(m))$, is the (undirected) graph with all elements of $m$ as vertices, and for distinct elements $n,m in m$, the vertices $n$ and $m$ are adjacent if and only if $n+m in t(m)$. in this paper we study the domination number of $t(ga...
A $\Gamma$-magic rectangle set $MRS_{\Gamma}(a, b; c)$ of order $abc$ is a collection $c$ arrays $(a\times b)$ whose entries are elements group $\Gamma$, each appearing once, with all row sums in every equal to constant $\omega\in \Gamma$ and column $\delta \in \Gamma$. In this paper we prove that for $\{a,b\}\neq\{2^{\alpha},2k+1\}$ where $\alpha$ $k$ some natural numbers, MRS$_{\Gamma}(a, b;c...
