Vertex semi-middle graph of a graph
In this communication, the vertex semi-middle graph of a graph $M_v(G)$ is introduced. We obtain a characterization of graphs whose $M_v(G)$ is planar, outerplanar and minimally non-outerplanar. Further, we obtain $M_v(G)$ is Eulerian, crossing number one and crossing number two.

Properties of Hereditary Hypergraphs and Middle Graphs [PDF]
AbstractThe middle graph of a graph G=( V, E) is the graph M(G) = (V∪E, E′), in which two vertices u, v are adjacent if either M is a vertex in V and v is an edge in E containing u, or u and v are edges in E having a vertex in common. Middle graphs have been characterized in terms of line graphs by Hamada and Yoshimura [7], who also investigated their ...

Middle school students’ graph skills and affective states about graphs
This survey design study was designed to test whether the graph skills and affective states of middle school students about graphs differ by their gender, grade level, and graph types (line, bar, and pie). The data collection instruments consisted of two

On Pathos Semitotal and Total Block Graph of a Tree [PDF]
The concept of pathos of a graph G was introduced by Harary [2], as a collection of minimum number of line disjoint open paths whose union is G. The path number of a graph G is the number of paths in pathos.

Graph equations for line graphs, total graphs, middle graphs and quasi-total graphs
Let G be a simple finite and connected graph with the vertex set V(G) and the edge set X(G). Let V'(G) be the family of all one-point subsets of V(G). Both the line graph L(G) of G and the total graph T(G) of G are standard graph theoretical concepts. The middle graph M(G) of G is the intersection graph of \(V'(G)\cup X(G)\) and the quasi-total graph P(

Computation of Vertex-Based Topological Indices of Middle Graph of Alkane CtH2t+2
Alkanes are the primary constituents of methane or natural gas that can also be found in volcanic crust. As a result of methane as a heat source, humans may cook without using any fuel in a volcanic environment.
