GRAPH THEORY Meaning and
Definition
-
Graph theory is a branch of mathematics that focuses on the study of graphs, which are mathematical structures that exhibit pairwise relationships between objects. In graph theory, a graph can be defined as a set of vertices or nodes, along with a set of edges or arcs that connect pairs of vertices. Graphs are commonly used to model and analyze various real-world systems, such as computer networks, social networks, transportation systems, and biological networks.
The study of graph theory involves the examination of several fundamental concepts and properties. One important concept is that of connectivity, which explores the presence and strength of connections or paths between vertices in a graph. Graph theory also studies the concept of cycles or circuits, which are closed paths that visit each vertex only once. Additionally, graph theorists investigate the concept of planarity, which explores whether a graph can be embedded in a two-dimensional plane without any edge intersections.
Various algorithms and techniques have been developed within graph theory to solve and analyze different problems. These algorithms can determine the shortest path between two vertices, identify the presence of cycles in a graph, calculate the number of possible paths, and establish the most efficient ways to traverse a given graph.
Graph theory has applications in numerous fields, including computer science, operations research, social sciences, physics, and biology. It serves as a powerful tool for analyzing the structures and properties of complex networks and has played a crucial role in the development of many technological advancements.

Etymology of GRAPH THEORY
The word "graph theory" is derived from the combination of the words "graph" and "theory".
The term "graph" was originally introduced in mathematics by the Swiss mathematician Leonhard Euler in the 18th century. Euler was studying a problem known as the "Seven Bridges of Königsberg", and he represented the city's landmasses and bridges as a diagram using dots and lines. He called this diagram a "graph", borrowing the term from Johannes Kepler's earlier use of the word to describe geometric drawings.
The word "theory" has its roots in ancient Greek. It comes from the Greek word "theōria", which means "a looking at, viewing, or contemplation". In the context of mathematics, theory refers to a systematic study, explanation, or framework of concepts and principles.
