Algorithms are presented for computing the form ring of a local ring A and a standard basis for any ideal I in A.
The basic ideas for the generalized Buchberger algorithm are given. It is shown how this algorithm allows to compute standard bases for ideals in localizations of polynomial rings at prime ideals. This technique is extended to rings of the kind $$A:=P_{{\mathfrak p}}/JP_{{\mathfrak p}}$$, where P is a polynomial ring, $$J\subset {\mathfrak p}$$ ideals, $${\mathfrak p}$$ prime. Some applications related to Hilbert function and regularity are marked.
