A note on the Brush Number of Jaco Graphs, $J_n(1), n \in \Bbb N
Johan Kok
The concept of the brush number was introduced for a simple connected undirected graph . This note extends the concept to a special family of directed graphs and declar…
Introduction to the McPherson number, of a simple connected graph
Johan Kok, Susanth C
The concept of the \emph{McPherson number} of a simple connected graph on vertices denoted by , is introduced. The recursive concept, called the \emph{McPherson recur…
Contemplating some invariants of the Jaco Graph,
Johan Kok, Susanth C
Kok et.al. [7] introduced Jaco Graphs (\emph{order 1}). In this essay we present a recursive formula to determine the \emph{independence number} with, $\Bbb…
The Derivative Degree Sequences of Finite Simple Connected Graphs are Parking Functions
Johan Kok
Parking functions are well researched and interesting results are found in the listed references and more. Some introductory results stemming from application to degree sequences o…
A note on the number of edges of the Jaco Graph, $J_n(1), n \in \Bbb N
Johan Kok, Vivian Mukungunugwa
Kok et.al. [3] introduced Jaco Graphs \emph{(order 1)}. It is hoped that as a special case, a closed formula can be found for the number of edges of a finite Jaco Graph . H…
A note on -Zagreb indices in respect of Jaco Graphs, and the introduction of Khazamula irregularity
Johan Kok, Vivian Mukungunugwa
The topological indices related to the \emph{first Zagreb index,} and the \emph{second Zagreb index,} are the oldest irregularity measures researched. Al…
