Abstract
The operation of 'disentangling' is the key to Feynman's operational calculi for non-commuting operators. Hence, formulas which simplify this procedure under various conditions are central to the subject. The main results here make it possible to carry out the disentangling in an iterative manner. The linear (alternatively, bilinear) term alluded to in the title of the paper refers to the first (alternatively, first and second) step (or steps) of the process. These results have many further consequences some of which are given in this paper.
