ResClasses -- Set-theoretic computations with [Res]idue [Classes] ================================================================= -- A GAP 4 Package -- Version 4.7.2 Author and Maintainer: Stefan Kohl, email@example.com Abstract ResClasses is a GAP 4 package for set-theoretic computations with residue classes of the integers and a couple of other rings. The class of sets which ResClasses can deal with includes the open and the closed sets in the topo- logy on the respective ring which is induced by taking the set of all residue classes as a basis, as far as the usual restrictions imposed by the finite- ness of computing resources permit this. For details on how to use the ResClasses package, see the package docu- mentation in the `doc' subdirectory -- either view its HTML version (chap0.html) with a browser, or its PDF version (manual.pdf) with a PDF viewer. Requirements This version of ResClasses needs GAP >=4.9.0, GAPDoc >=1.5.1, Polycyclic >=2.11 and Utils >=0.40. All required packages are already present in an up- to-date standard GAP installation. ResClasses can be used on all platforms for which GAP is available. It is completely written in the GAP language and does neither contain nor require external binaries. Installation Like any other GAP package, ResClasses is usually installed in the pkg/ sub- directory of the GAP distribution. This is accomplished by extracting the package archive file in this directory. After this you can load the package as usual via LoadPackage( "resclasses" );. For further advice on questions of technical nature please see the chap- ter `Installation and Auxiliary Functions' in the manual. Distribution and Updates New releases of this package are put online on the package web page https://gap-packages.github.io/resclasses/ --- If you install ResClasses or if you use it in some of your work, then please let me know.
