We propose a framework where Fer and Wilcox expansions for the solution of differential
equations are derived from two particular choices for the initial transformation that seeds the product
expansion. In this scheme, intermediate expansions can also be envisaged. Recurrence formulas are
developed. A new lower bound for the convergence of theWilcox expansion is provided, as well as
some applications of the results. In particular, two examples are worked out up to a high order of
approximation to illustrate the behavior of the Wilcox expansion. [-]
