! 12: <p>
! 13: <a href="http://www.openxm.org">The OpenXM project </a>
! 14: provides a package of mathematical software systems,
! 15: which are integrated by
! 16: the OpenXM protocol.
! 17: OpenXM is an abbreviation of Open message eXchange for Mathematics.
! 18:
! 19: The computer algebra system
! 20: <a href="http://www.math.kobe-u.ac.jp/Asir/index.html">
! 21: Risa/Asir</a>
! 22: <img src="file:///usr/share/pixmaps/hopo_std_color.xpm"/>,
! 23: which is made in Japan,
! 24: is a main client of the package and
! 25: all software systems in the package can be used from Risa/Asir.

! 28: <h2> <font color="red"> How to start Risa/Asir </font> </h2>
! 29: From the KDE menu, choose <br>
! 30: <font color="green"> Application </font>

! 34: <font color="green"> Asir(OpenXM) <img src="file:///usr/share/pixmaps/hopo_std_color.xpm"/>
! 35: </font>
! 36: <br>
! 37: In order to use Asir(OpenXM),
! 38: your computer must be connected to the internet, because
! 39: a part of Risa/Asir is downloaded from ftp.math.kobe-u.ac.jp. <br>
! 40: <font color="cyan">
! 41: NOTE:
! 42: A part of Asir cannot be included in the CD because of a restriction
! 43: of the Risa/Asir license and the part is downloaded from the internet
! 44: after you agree with the license.
! 45: The size of the part is less than 2 Mega bytes.
! 46: The part is saved under your home directory
! 47: with the names .asir-tmp, .TeXmacs, .asirrc.
! 48: If you have a USB memory, you can save the files of your home directory
! 49: to the USB memory.
! 50: Choose the KDE menu <br>
! 51: knoppix --> configure --> create persistent home directory <br>
! 52: As to details, see a knoppix manual.
! 53: </font>
! 54: <br>
! 55: Once you downloaded, you can use Asir(OpenMX) from the TeXmacs, too.
! 56: In the TeXmacs menu, choose<br>

! 67: <h2> <font color="red"> What kind of computation can I do by Risa/Asir? </font> </h2>
! 68: Here are some examples
! 69: <ol>
! 70: <li> <font color="blue"> fctr(x^100-1); </font>
! 71: Factorization of x <sup> 100 </sup> - 1
! 72: <li> <font color="blue">
! 73: ifplot(x^3-y^2);
! 74: </font>
! 75: Drawing the zero set of x <sup> 3 </sup> - y <sup> 2 </sup> = 0.
! 76: <li> <font color="blue">
! 77: gnuplot.heat(0.0001,100);
! 78: </font>
! 79: Solving the heat equation by using the forward difference scheme.
! 80: The time step is 0.0001.
! 81: <li> <font color="blue">
! 82: dp_gr_main([x^2+y^2-4,x*y-1] | v=[x,y], order=[[x,1]]);
! 83: </font>
! 84: <br>
! 85: Computation of the Grobner basis of
! 86: x <sup> 2 </sup> +y <sup> 2 </sup> -4, x y -1
! 87: with the weight 1 for the variable x and the weight 0
! 88: for the variable y.
! 89: <li> <font color="blue">
! 90: F=[x^2+y^2-4,x*y-1]; V=[x,y];
! 91: dp_gr_main(map(dp_ptod,F,V) | v=V, order=[[x,1]]);
! 92: </font>
! 93: The same computation, but the answer is given by DP (distributed polynomial).
! 94: <li> Others:
! 95: A faster Grobner basis computation (nd_gr_main),
! 96: primary ideal decomposition (primadec), factorization in algebraic
! 97: extensions of Q (afctr), computation in the ring of differential operators
