Star metric dimension of complete, bipartite, complete bipartite and fan graphs
One of the topics in graph theory that is interesting and developed continuously is metric dimension. It has some new variation concepts, such as star metric dimension.

Domination number of middle graphs [PDF]
In this paper, we study the domination number of middle graphs. Indeed, we obtain tight bounds for this number in terms of the order of the graph G. We also compute the domination number of some families of graphs such as star graphs, double start graphs,

Constructions of new integral graph families
We construct new families of integral graphs by considering complete products, unions and point identifications of complete graphs and complete bipartite graphs.

It has been shown in [S. Cichacz, A. Görlich, Decomposition of complete bipartite graphs into open trails, Preprint MD 022, (2006)] that any bipartite graph \(K_{a,b}\), is decomposable into open trails of prescribed even lengths.

On Subgraphs of the Complete Bipartite Graph [PDF]
G(n) denotes a graph of n vertices and Ḡ(n) denotes its complementary graph. In a complete graph every two distinct vertices are joined by an edge. Let Ck(G(n)) denote the number of complete subgraphs of k vertices contained in G(n). Recently it was proved [1] that for every k1where the minimum is over all graphs G(n).

Energy of Certain Classes of Graphs Determined by Their Laplacian Degree Product Adjacency Spectrum
In this study, we investigate the Laplacian degree product spectrum and corresponding energy of four families of graphs, namely, complete graphs, complete bipartite graphs, friendship graphs, and corona products of 3 and 4 cycles with a null graph.

Strong Geodetic Number of Complete Bipartite Graphs and of Graphs with Specified Diameter [PDF]
The strong geodetic problem is a recent variation of the classical geodetic problem. For a graph G, its strong geodetic number sg(G)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb ...

A Note on the Equitable Choosability of Complete Bipartite Graphs [PDF]
In 2003 Kostochka, Pelsmajer, and West introduced a list analogue of equitable coloring called equitable choosability. A k-assignment, L, for a graph G assigns a list, L(v), of k available colors to each v ∈ V (G), and an equitable L-coloring of G is a ...

P_4-Colorings and P_4-Bipartite Graphs [PDF]
A vertex partition of a graph into disjoint subsets V_is is said to be a P_4-free coloring if each color class V_i induces a subgraph without chordless path on four vertices (denoted by P_4).
