NCAlgebra announcement

  • To: mathgroup at yoda.physics.unc.edu
  • Subject: NCAlgebra announcement

We have a NonCommutative Algebra package which extends
the one in the HEPHYSICS directory (actually this 
program was our base code). We have not put it on any
bulletin boards yet, but it is availible through anonymous
ftpm (see below).

Please let us know if you are using the program so that
we can send you updates/know how popular the program is.

Comments/bug reports are welcome.

                               NCALGEBRA

                              Version 0.1



(****************************************************************************)

     Thanks you for your interest in NCAlgebra.  This message contains the
     information necessary for you to use anonymous ftp to transfer the 
     files from our site to yours. The ONLY thing which you have to
     do to get the NCAlgebra package is to follow the following sample
     terminal session. 

     NCAlgebra is at osiris.ucsd.edu, in the pub/ncalg directory.  Below 
     is a record of an actually ftp session. What the user types is 
     underlined.  Quoted expressions describe what should be typed.
     (e.g., where you see "Any thing will do.", you may type anything
     you want). Ignore all timing data.

     Note: If you are unfamiliar with ftp, then note that after the
     command "mget *", the computer will respond with the prompt 
     "mget CEEP?". You should hit the return key to indicate that 
     you do indeed want to get the file CEEP. The computer will then
     prompt you for the next file and you must hit the return key 
     again. Even though there are about thirty files, the whole
     process should take less than five minutes.
     
     
     BELOW IS A SAMPLE SESSION. IF YOU FOLLOW IT, THEN YOU WILL BE
     ABLE TO GET A COPY OF THE NCALGEBRA PACKAGE.

     YOU CAN HAVE YOUR LOCAL COMPUTER "GURU" FOLLOW THE BELOW 
     INSTRUCTIONS AND INSTALL NCALGEBRA AS AN OFFICIAL MATHEMATICA
     PACKAGE. ONCE THIS IS DONE, EVERYONE USING THE COMPUTER MAY
     USE NCALGEBRA.

     We have included a file called "ListofFilesAndSizes" in the directory
     so that you can compare filenames and filesizes by Kilobyte blocks.
     
     This can be accomplished by typing the following UNIX commands,
     
          ls -s -1 > MyFiles; diff MyFiles ListofFilesAndSizes
     
     If what you have is identical to what we have, there should be NO
     output from the diff command.  If there is a difference, then try
     ftp again. If the difference is "small", talk to a local expert.

     We are interested in knowing who has NCAlgebra, so that 
     we are able to inform them that new versions of the code 
     are available, etc. PLEASE send us a email message so 
     that we know that you are using the program.

     The documentation for NCAlgebra is contained in the file
     NCDOCUMENT. Printing out this file to a printer is the best 
     first step.
     
     We can email NCAlgebra, if necessary.
     
               Email any questions, comments or requests to 
       
     
                          ncalg at osiris.ucsd.edu
