In this thesis we describe dualities in directed as well as undirected graphs based on tools such as width-parameters, obstructions and substructures. We mainly

The study of directed graphs (digraphs) has developed enormously over recent decades, yet the results are rather scattered across the journal literature. This i

In this research book, there are some research chapters on “Neutrosophic Duality”. With researches on the basic properties, the research book starts to make
