A subset S of vertices of a graph G is a determining set for G if every automorphism of G is uniquely determined by its action on S. The determining number of a graph G is the smallest integer r such that G has a determining set of size r. In this pa

Let $M$ be a right module over a ring $R$, $tau_M$ a preradical on $sigma[M]$, and$Ninsigma[M]$. In this note we show that if $N_1, N_2in sigma[M]$ are two$tau_M$-lifting modules such that $N_i$ is $N_j$-projective ($i,j=1,2$), then $N=N_1oplusN_2$ i

We introduce the equitable distinguishing chromatic number $$\chi _{ED}(G)$$ of a graph G as the least number k such that G has an equitable coloring with k colors that is only preserved by the trivial automorphism. The equitable distinguishing chrom

espanolIn this note we introduce L-⊕-supplemented modules as a proper generalization of ⊕-supplemented modules. A module M is called I-⊕-supplemented if for every φ ∈ EndR (M), there exists a direct summand L of M such that Imφ + L = M and

Let $R$ be a ring. In this article, we introduce and study relative dual Baer property. We characterize $R$-modules $M$ which are $R_R$-dual Baer, where $R$ is a commutative principal ideal domain. It is shown that over a right noetherian right hered

Lifting modules plays important roles in module theory. H-supplemented modules are a nice generalization of lifting modules which have been studied extensively recently. In this article, we introduce a proper generalization of H-supplemented modules

The distinguishing number D ( G ) of a graph G is the least number k such that G has a coloring with k colors that is only preserved by the trivial automorphism. In this paper, we study the distinguishing number of hierarchical products of graphs. Th
