Installation of the Janet and Involutive package
------------------------------------------------
The Maple packages Janet, Involutive and JanetOre are
developed at Lehrstuhl B fuer Mathematik, RWTH Aachen,
http://wwwb.math.rwth-aachen.de, Copyright (C) 2000-2007.
In these packages the concept of involutive division
is implemented. The package Janet handles linear
partial differential equations, the packages Involutive
deals with polynomial equations, and the package JanetOre
treats equations defined by certain linear functional
operators.
The following description of the installation process
assumes that you are going to use the packages Janet,
Involutive and JanetOre in Maple 8 or newer versions of
Maple.
1. Create a directory which is supposed to contain
all files of the packages Janet, Involutive and JanetOre,
e.g. mkdir /usr/local/lib/Janet.
2. At http://wwwb.math.rwth-aachen.de/Janet,
select the appropriate version of the package ("Maple8"
etc.) and download the following files into the
directory chosen in 1.:
Involutive.ind
Involutive.lib
Janet.ind
Janet.lib
JanetOre.ind
JanetOre.lib
maple.hdb
(These files contain the Janet, Involutive and JanetOre
package and the help data base for both packages.)
3. Ensure that the directory which you have chosen in 1.
is listed in the global Maple variable 'libname'
(see ?libname in Maple for details).
Then the packages can be loaded via
with(Janet);
resp.
with(Involutive);
resp.
with(JanetOre);
Moreover, help pages are available for the functions of
these packages, see ?Janet, ?Involutive, ?JanetOre.
The program JB is compiled for Linux (Pentium Pro).
The authors are V. P. Gerdt and Yu. A. Blinkov,

It is an implementation of the involutive basis algorithm
in C++. Some modifications have been done by D. Robertz
in order to adapt it to the requirements of the Maple
package.
The package Involutive offers an interface to this
program within Maple. Therefore the program file JB
has to be copied into a directory which is included in $PATH.
The commands invoking this program are
InvolutiveBasisFast, PolInvReduceFast, SyzygyModuleFast,
and GroebnerBasisFast.
After installing Janet, Involutive or JanetOre, it would be
helpful if you could send us a short e-mail to
janet@momo.math.rwth-aachen.de
which explains who you are and which Maple version
you use.
If you find any bug in Janet, Involutive or JanetOre,
please send an e-mail to janet@momo.math.rwth-aachen.de.
