Random Cyclic Triangle-Free Graphs of Prime Order
Journal of Mathematics, 2021 Cyclic triangle-free process (CTFP) is the cyclic analog of the triangle-free process. It begins with an empty graph of order n and generates a cyclic graph of order n by iteratively adding parameters, chosen uniformly at random, subject to the ...

Relatively Prime Detour Domination Number of Some Switching Graphs
Ratio Mathematica, 2023 In this paper, we introduce the concept of relatively prime detour domination number for switching graph. If a set S ⊆ V is a detour set, a dominating set with at least two elements, and has (deg(u), deg(v)) = 1 for each pair of vertices u and v, then it

Finite groups whose character degree graphs coincide with their prime graphs [PDF]
, 2018 Veliev, Oktay A. (Dogus Author)In the literature, there are several graphs related to a finite group G. Two of them are the character degree graph, denoted by ΔG), and the prime graph ΓG), In this paper we classify all finite groups whose character ...

On the power graphs of elementary abelian and extra special $p$-groups [PDF]
International Journal of Group Theory, 2021 For a given odd prime $p$, we investigate the power graphs of three classes of finite groups: the elementary abelian groups of exponent $p$, and the extra special groups of exponents $p$ or $p^2$. We show that these power graphs are Eulerian for

Prime labelings on planar grid graphs
Theory and Applications of Graphs, 2022 It is known that for any prime p and any integer n such that 1≤n≤p there exists a prime labeling on the pxn planar grid graph PpxPn.

Prime Labeling of H- Super Subdivision of Y-tree Related Graphs
Ratio Mathematica, 2023 A graph G with p points is called a prime labeling , if it possible to label the points x 2 V with distinct labels f(x) from f1;2; :::; pg in such a way that for each line e = uv gcd (f(u); f(v)) = 1 .

Prime ideal graphs of commutative rings
Indonesian Journal of Combinatorics, 2022 Let R be a finite commutative ring with identity and P be a prime ideal of R. The vertex set is R - {0} and two distinct vertices are adjacent if their product in P. This graph is called the prime ideal graph of R and denoted by ΓP.
