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 theory is a branch of mathematics concerned about how networks can be encoded, and their properties measured. 1. Basic Graph Definition.

"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 ... " - Graph and network theory
