✦ Synopsis

The increasingly popular S and O notation in causal-loop diagrams has a serious flaw, which suggests it should be purged from educational, consulting, and publication practice. The flaw traces to the inability of the notation to capture correctly the influences of flows into and out of stocks, which often appear implicitly in word-and-arrow diagrams. In contrast, the older notation of plus and minus signs handles the problem well.

Scalar two-loop diagrams are calculated analytically in massive cases needed for the computation of boson and fermion propagators in QED and QCD by the causal method of Epstein and Glaser. It is demonstrated that this method, which is the basis for the so-called dispersive methods, provides many adv

When, during causality assignment in bond graph modelling, one is faced with a causality indetermination, one is told to assign "arbitrary" causalities. No rule is given to help except of course that of consistency. However, the dtxerent consistent causal assignments do not necessary lead to the sam
