The Armendariz Graph of a Ring

Discussiones Mathematicae - General Algebra and Applications, 2018
In this paper we initiate the study of Armendariz graph of a commutative ring R and investigate the basic properties of this graph such as diameter, girth, domination number, etc.

A subexponential construction of graph coloring for multiparty computation

Journal of Mathematical Cryptology, 2014
We show the first deterministic construction of an unconditionally secure multiparty computation (MPC) protocol in the passive adversarial model over black-box non-Abelian groups which is both optimal (secure against an adversary who possesses any ...

Green's graphs of a semigroup

Open Mathematics
Let SS be a semigroup. In this study, we first introduce the Green’s digraphs and Green’s graphs related to the Green’s relations L{\mathscr{L}}, R{\mathscr{R}}, and J{\mathscr{J}} of SS.

Classifying pentavalent symmetric graphs of order 12pq

Open Mathematics
A graph is said to be symmetric if its automorphism group is transitive on its arcs. Guo et al. (Pentavalent symmetric graphs of order 12p, Electron. J. Combin. 18 (2011), no. 1, #P233, DOI: https://doi.org/10.37236/720) and Ling (Classifying pentavalent

Forbidden subgraphs of TI-power graphs of finite groups

Open Mathematics
Given a finite group GG with identity ee, the TI-power graph (trivial intersection power graph) defined on GG, denoted by Γ(G)\Gamma \left(G), is an undirected graph with vertex set GG where distinct vertices aa and bb are adjacent if ⟨a⟩∩⟨b⟩={e}\langle ...
