Web12. Graph theory and topology, while they certainly enrich each other, are quite different subjects. A graph is a discrete object with many variants. It can be directed or undirected, it can have multiple edges between two vertices or it may not. Typical questions about graphs tend not to be of a local nature.WebJul 12, 2014 · 1 Answer. Sorted by: 4. A connected graph with two vertices of degree one and the rest of degree two is called a path.

WebJan 29, 2024 · It is known that any tree has one or two weight centers. A tree is called a two-branch tree if the removal of all its weight centers results in a forest with exactly two components. In this paper we obtain a sharp lower bound for the radio number of two-branch trees which improves a known lower bound for general trees.
