From the reviews: "This monograph pretends to describe the start point for developing a systematic way for solving linear partial differential equations (PDE's) based on the Loewy's decomposition method, working in an proper ring of differential operators and including algorithmic alternatives for several problems considered in classic literature. ... this monograph is truly a guide book for the problem of decomposing differential operators, written in a very clear and objective language, and providing the necessary tools towards more general problems."
