Network analysis is a research area that focuses on studying the structure, behavior, and dynamics of complex networks. These networks can range from social networks, biological networks, transportation networks, to communication networks. Network analysis involves using mathematical and computational tools to analyze the relationships and interactions between nodes (individual entities) and edges (connections between nodes) in a network. Researchers in this field seek to uncover patterns, properties, and properties of networks, as well as understand how information, resources, or influence flow through them. Network analysis has applications in various domains, including sociology, biology, computer science, and engineering.
