Introduction

The computer algebra system asir can use servers, which support the OpenXM protocols (Open message eXchange for Mathematics, http://www.openxm.org), as components. The interface functions to call these servers are loaded by loading the file `OpenXM/rc/asirrc'. This file is automatically loaded in "Risa/Asir(OpenXM distribution)", which we call OpenXM/Risa/Asir in this document. This document explains these interface functions for asir and several mathematical and utility functions written in the user languages of Risa/Asir. These mathematical and utilitiy functions are outcome of the Asir-contrib project.

As to technical details on the OpenXM protocols, see `openxm-en.tex' at `$(OpenXM_HOME)/doc/OpenXM-specs'.

How to load Asir/Contrib

With loading `OpenXM/rc/asirrc', we can use most functions in Asir/Contrib. The OpenXM/Risa/Asir reads this file, which is specified by the ASIR_CONFIG environmental variable, when it starts. The file `names.rr' is the top level file of the Asir/Contrib. Most other files are loaded from `names.rr'. Some packages are not loaded from `names.rr' and they must be loaded individually.

A sample of `asirrc' to use Asir/Contrib. 

load("gr")$
load("primdec")$
load("katsura")$
load("bfct")$
load("names.rr")$
load("oxrfc103.rr")$
User_asirrc=which(getenv("HOME")+"/.asirrc")$
if (type(User_asirrc)!=0) {
   if (!ctrl("quiet_mode")) print("Loading ~/.asirrc")$
   load(User_asirrc)$
}else{ }$
end$

Asir-contrib for Windows

A part of Asir-contrib works on Windows. The following functions and components work on windows; the outer component sm1 and functions in asir-contrib which do not call outer components. In the cygwin environement, the outer components sm1, phc work. The other outer components do not work.

The following functions do not work on Windows. Some of them work in the cygwin environment of Windows.

   todo_parametrize/todo_parametrize_toc




With loading the file todo_parametrize/todo_parametrize.rr
the function paramerize is installed.
The function finds a parametric expression of a given rational curve.
As to details, see
See section `' in A package for algebraic curves (in Japanese).

[1426] parametrize(y^2+x^3);
[-t,1,t^3,(-x)/(y)]






taji_alc




With loading the file taji_alc.rr
functions for algebraic local cohomology groups in one variable are imported.
