Produktbeschreibung

"...A nice feature of the book [is] that at various points the authors provide examples, or rather counterexamples, that clearly show what can go wrong...This is a nicely-written book [that] studies algebraic differential modules in several variables."

Rezensionen

"If I had to summarize the differences in the exposition in one sentence, I would say that the authors manage to make the transition from a research monograph to an exposition that reads more like an advanced textbook, while retaining the rigor and the scientific interest; it is an example of what may be called a 'research textbook'." ( Adolfo Quirós, Mathematical Reviews, January, 2023)
