Our results contribute to the growing fields of hybrid planarity and of graph drawing beyond planarity. Full article

WebDefinition 20. A graph G is planar if it can be drawn in the plane in such a way that no pair of edges cross. Attention should be paid to this definition, and in particular to the word ‘can’. Whether or not a graph is planar does not depend on how it is actually drawn. Instead, planarity depends only on whether it ‘can’ be drawn in ...

WebThis beginner course covers the fundamental concepts in graph theory and some of its applications. Graph Theory can model and study many real-world problems and is applied in a wide range of disciplines. In computer science, graph theory is used to model networks and communications; Google search, Google maps and social medias all use it.
