Short description

The REDUCE package CALI contains algorithms for computations in commutative algebra closely related to the Groebner algorithm for ideals and modules. There are facilities for local computations, using a modern implementation of Mora's standard basis algorithm, that works for arbitrary term orders. This reflects the full analogy between modules over local rings and homogeneous (in fact H-local) modules over polynomial rings.

The current version 2.2 was finished at Febr. 14, 1995.

The package (tested with Reduce 3.5-3.7) is available as tgz-File and contains the package sources, test and demo files.
