Maximal Energy Bipartite Graphs

open access: yesGraphs and Combinatorics, 2003
Given a graph $G$, its energy $E(G)$ is defined to be the sum of the absolute values of the eigenvalues of $G$. This quantity is used in chemistry to approximate the total $\pi$-electron energy of molecules and in particular, in case $G$ is bipartite ...

Signed mixed dominating functions in complete bipartite graphs

International Journal of Computer Mathematics, 2014
Let G=(V, E) be a simple graph with vertex set V and edge set E. A signed mixed dominating function (SMDF) of G is a function f: V∪E→{−1, 1} such that for every element x∈V∪E, where Nm(x) is the set, called mixed neighbourhood of x, of elements of V∪E adjacent or incident to x.

Mixing patterns and communities on bipartite graphs on web-based social interactions

2009 16th International Conference on Digital Signal Processing, 2009
We use bipartite graph representation of interactions between users of Web databases, such as data about art subjects (books, movies, music records), where users interact via posting comments related to a specific subject. We study patterns of clustering which emerge through the common interests of users.

Mixed-cycle-V-super magic decomposition of complete bipartite graphs

Asian-European Journal of Mathematics
An [Formula: see text]-magic labeling in an [Formula: see text]-decomposable graph [Formula: see text] is a bijection [Formula: see text] such that for every copy [Formula: see text] in the decomposition, [Formula: see text] is constant. [Formula: see text] is said to be [Formula: see text]-[Formula: see text]-super magic if [Formula: see text].
