Investigating the correlations between graph metrics in various networks is a prosperous research topic that only starts to evolve. Knowledge about graph metrics interrelations may be beneficial in many other aspects of networks studying, starting from optimizing computations to even detecting...

A graph is called regularable if it is possible to label its edges with integers so that the sum of the integers assigned to the edges incident to the vertices are all same, say equal to . Clearly if the given graph is regular of degree then there is no need to find an edge-assignment; simply...

In this article we propose a new graphical method to help us to uncover potential outliers in multivariate samples. The idea behind the method is to analyze the behavior of a growing neighborhood of each data point. This method is very robust and permits to find outliers in very complex structures

We define an between finite simple graphs and use it to define an equivalence relation on the set of natural numbers. The least integers of the equivalence classes serve as canonical code numbers for graphs and this new integer sequence we call the sequence of Characterizations of the...
