WebThe nature of the graphs depends on the interactions and coupling constants of your model -- that is, on the action. An (oversimplified) example: Suppose you only had one degree of freedom, x, and the action is S 0 ( x) = i ℏ x 2 / 2, so that exp ( i S 0 / ℏ) = exp ( − x 2 / 2). (You can ignore ℏ in this example.) WebGraph (discrete mathematics) A graph with six vertices and seven edges. In discrete mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

WebNetwork theory is a part of graph theory: a network can be defined as a graph in which nodes and/or edges have attributes (e.g. names). A graph is defined by the structural information contained in its adjacency matrix, a network may have an arbitrary large amount of ancillary information on top of it. Edges can have attributes such as capacity ... WebBasic tool: graph theory, the mathematical study of graphs/networks. I We use the terms “graph” and “network” interchangeably.
