Applications on color (distance) signless laplacian energy of annihilator monic prime graph of commutative rings

Ain Shams Engineering Journal
In this study, we define the structure formation of the annihilator monic prime graph of commutative rings, whose distinct vertices X and J satisfies a condition annXJ≠annX⋃ann(J), graph is denoted by AMPG(Zn[x]/〈fx〉).

Some new relations between Sombor index and graph energy

Examples and Counterexamples
Let G be a graph with {v1,…,vn} being vertices and di being the corresponding vertex degrees. The Sombor index of G is denoted by SO(G) and is defined by SO(G)=∑i∼jdi2+dj2 where i∼j means there exists an edge between the vertices vi and vj.

On the Distribution of Vertex Energy of Connected Non-Regular Non-Bipartite Integral Graphs with Maximum Vertex Degree Four

Scientific Annals of Computer Science
The energy of a vertex in a graph plays a very important role in terms of its contribution to the total energy of a graph, a significant graph invariant in the field of chemical graph theory.
