Comparative Study of Planar Octahedron Molecular Structure via Eccentric Invariants
A branch of graph theory that makes use of a molecular graph is called chemical graph theory. Chemical graph theory is used to depict a chemical molecule. A graph is connected if there is an edge between every pair of vertices.

Hausdorff of a cycle in topological graph
The main purpose of the paper is to bring together two areas in which strong relation, graph theory and topological spaces. And derive interesting formula for the set that contains all minimal dominating sets(MDS) and ( -set). Some separation axioms are

Problems in extremal graph theory [PDF]
We consider a variety of problems in extremal graph and set theory. The {\em chromatic number} of $G$, $\chi(G)$, is the smallest integer $k$ such that $G$ is $k$-colorable.

Wavelets on graphs via spectral graph theory [PDF]
We propose a novel method for constructing wavelet transforms of functions defined on the vertices of an arbitrary finite weighted graph. Our approach is based on defining scaling using the the graph analogue of the Fourier domain, namely the spectral decomposition of the discrete graph Laplacian $ $.

On the Generation, Structure, and Symmetries of Minimal Prime Graphs [PDF]
In this paper we continue the study of prime graphs of finite solvable groups. The prime graph, or Gruenberg-Kegel graph, of a finite group G has vertices consisting of the prime divisors of the order of G and an edge from primes p to q if and only if G contains an element of order pq.

The Role of Graph Theory in System of Systems Engineering
The world of system of systems engineering (SoSE), and consequently systems engineering, is currently being reformalized so as to provide greater functionality, integration, and extensibility into designed systems of systems (SoS).

Network design based on graph theory [PDF]
The continuous technology development has been forcing the world to share information or access to some specific shared data. "Being isolated" is no longer a solution "to protect oneself" against any threats. This project aims to define a new design of a

Logspace computations in graph products
We consider three important and well-studied algorithmic problems in group theory: the word, geodesic, and conjugacy problem. We show transfer results from individual groups to graph products.
