Network Theory

Definition

Network theory is the study of graphs as a representation of either symmetric or asymmetric relations between discrete objects. It is essential in understanding how different entities interact within a system, particularly in the analysis of structures like social networks, transportation systems, and communication pathways. By applying network theory, one can analyze properties such as connectivity, flow, and the dynamics of systems, which are vital in the context of tropical eigenvalues and eigenvectors.
