## What is graph theory?

Graph theory is a branch of mathematics that studies graphs, which are abstract structures that consist of vertices (also called nodes or points) and edges (also called links or lines) that connect them. Graphs can be used to model many phenomena in various fields, such as networks, social relations, communication, transportation, cryptography, biology, chemistry, physics, and more.

Graph theory has many applications and algorithms that can solve problems such as finding the shortest path between two vertices, finding the maximum flow in a network, finding the minimum spanning tree in a graph, finding the coloring or partitioning of a graph, finding the connectivity or components of a graph, finding the cycles or paths in a graph, finding the cliques or subgraphs in a graph, finding the matchings or assignments in a graph, finding the planarity or embedding of a graph, finding the hamiltonicity or eulericity of a graph, and more.

## Who is Frank Harary?

Frank Harary (1921-2005) was an American mathematician who was one of the pioneers and founders of graph theory. He was a professor at the University of Michigan for most of his career and published over 700 papers and 15 books on graph theory and related topics. He was also known for his contributions to social network analysis, combinatorics, geometry, topology, algebra, game theory, and more.

Frank Harary was a charismatic and influential teacher who inspired many students and researchers to pursue graph theory.
