Nonlocal, noncommutative diagrammatics and the linked cluster Theorems [PDF]

open access: yes, 2011
Recent developments in quantum chemistry, perturbative quantum field theory, statistical physics or stochastic differential equations require the introduction of new families of Feynman-type diagrams. These new families arise in various ways.
