In this paper, we show how to conjointly use module theory and constructive homological algebra to obtain general conditions for a matrix R of functional operators (e.g., differential/shift/time-delay operators) to be equivalent to a block-triangular or blockdiagonal matrix $$\bar{R}$$ (i.e., conditions for the existence of unimodular matrices V and W satisfying that $$\bar{R} = V RW$$). These results allow us to simplify the study of many linear functional systems – particularly differential… Expand
