The QPA package for GAP 4.5 ================================== Version 1.27; December 16th, 2017 Copyright (C) 2010 The QPA-team, https://folk.ntnu.no/oyvinso/QPA/ Introduction ------------ The "Quivers and Path Algebras" team has as a goal to develop a GAP package(s) for carrying out computations for finite dimensional quotients of path algebras over the fields that are available in GAP. The package we aim to develop for GAP is called QPA for Quivers and Path Algebras. QPA is designed as a GAP >= 4.5.x share package providing new functions in noncommutative algebra. For the current functions provided by QPA follow the URL https://folk.ntnu.no/oyvinso/QPA/ and look at WhatYouCanDoList. Contents -------- The following should be included with this version of QPA. CHANGES - files containing the history of changes in QPA since version 1.05. LICENSE - the license governing QPA usage PackageInfo.g - contains metainformation about the package README - this file doc - the user manuals examples - manual examples in separate files, chapterwise init.g - package initialization lib - the GAP source code read.g - package initialization tst - tests for the package version - contains the version number of the latest version Installation ------------ Since the release of GAP version 4.7.8, the package QPA is distributed with GAP, so if you download this version or any later version QPA will be installed at the same time as GAP is installed. Follow the instructions for installing GAP on the web page http://www.gap-system.org/Download/index.html After having successfully started GAP, give the command gap> LoadPackage("qpa"); which loads QPA and you can start using QPA. For GAP version 4.7.7 or older, or you want a newer version of QPA than the one that is distributed with GAP, follow the following instructions: 1. Locate a pkg-directory where GAP searches for packages, see 9.2 GAP Root Directories in the GAP manual for more information. 2a. Download a release of QPA from https://github.com/gap-packages/qpa/releases and unpack it in the pkg-directory you located in 1. 2b. Alternatively, clone the git-repository of QPA by giving the following command: git clone https://github.com/gap-packages/qpa.git qpa when you are in the pkg-directory you located in 1. For making the documentation for QPA give the command MakeQPADocumentation(); inside a gap-session with QPA loaded. For later obtaining the latest version of QPA, give the command git pull when you are inside the qpa-directory. Using QPA ---------- To load the QPA-package, give the command LoadPackage("qpa"); To avoid having to load QPA each time you use GAP, you can add "qpa" to the user preference PackagesToLoad, as explained in https://firstname.lastname@example.org/msg02528.html See the user manual in the doc directory for more information regarding the use of QPA, or follow the URL https://folk.ntnu.no/oyvinso/QPA/manual.pdf to see the current manual/documentation of QPA (still work in progress, not brilliant at this point). Contact ------- If you have a question or encounter any problems regarding QPA, you can either: * contact one of the QPA-team members, see the webpage https://folk.ntnu.no/oyvinso/QPA or * report an issue at https://github.com/gap-packages/qpa/issues/new
