Instead we restrict ourselves exactly to those topics, definitions and properties, which play a major role throughout the sequel.

The elements of these rings exhibit a behaviour which is similar to that of ordinary, commutative polynomials, allowing them to be approached computationally. Left PBW rings are actual

In this way, the reader may easily compare the commutative and the non-commutative approach.

In the present chapter we will generalize this approach and show how it applies as well to submodules of the free module ..Actually, it appears that this set-up may also be used to calculate syzygy modules, both in the ideal and (more generally) the module case.

However, it appears that this approach is highly inefficient from the computational point of view, mainly due to the necessary use of the lex ordering (or, more generally, any elimination ordering). Actually, lots of effort has been spent in the past in order to avoid the use of elimin

Das Leistungs- und Produktportfoliootion is defined by using chains of (two-sided) prime ideals, it only makes sense for rings having “many” two-sided ideals. Fortunately, for finitely generated k-algebras ., we may define the so-called Gelfand-Kirillov dimension GKdim(.), which is a far better invariant and which, moreover, coincide

We include algorithms which treat essential aspects like ideals and (bi)modules, the calculation of homological dimension and of the Gelfand-Kirillov dimension, the Hilbert-Samuel polynomial, primality tests for prime ideals, etc.

We show how Buchberger’s approach generalizes to the noncommutative case. In particular, we will see that Gr?bner bases always exist and that reduced Gr?bner bases are unique.
