On the Pendant Number of Certain Graphs

P. G. R. S. Ranasinghe & L. R. M. K. R. Jayathilaka · Journal of Advances in Mathematics and Computer Science · 2023

The present study investigates the pendant number of certain graph classes; complement, line graphs, and total graphs. The pendant number is the minimum number of end vertices of paths in a path decomposition of a graph. A path decomposition of a graph is a decomposition of it in...

On a Question of Constructing Mӧbius Transformations via Spheres and Rigid Motions

P. G. R. S. Ranasinghe & R. A. S. T. Abeysekara · Asian Research Journal of Mathematics · 2022

A Mӧbius Transformation or a Fractional Linear Transformation is a complex-valued function that maps points in the extended complex plane into itself either by translations, dilations, inversions, or rotations or even as a combination of the four mappings. Such a mapping can be c...

On a Question of Prime Labeling of Graphs

A. M. C. U. M. Athapattu & P. G. R. S. Ranasinghe · Journal of Advances in Mathematics and Computer Science · 2021

In the field of graph theory, the complete graph  of  vertices is a simple undirected graph such that every pair of distinct vertices is connected by a unique edge. In the present work, we introduce planar subgraph  of  with maximal number of edges . Generally,  does not admit pr...
