[Reduce-algebra-developers] factorization issue...

[Michael T. <tu...@fh...>]

Dear all,
using the svn version of yesterday on Mac OS X Lion gives:

[mba:~/Documents/reduce-algebra/trunk] tuexen% bin/redcsl -w
Reduce (Free CSL version), 16-Nov-11 ...

1: setmod 2; on modular;

1


3: factorize(x^2+1);

{{x + 1,0}}

I would expect {{x + 1,2}}.

Another try:

4: factorize(x^4+x^3+x+1);

   2
{{x  + x + 1,1},{x + 1,0}}

where I would expect

   2
{{x  + x + 1,1},{x + 1,2}}

However,

5: factorize(x^3+1);

   2
{{x  + x + 1,1},{x + 1,1}}

works.

So it looks like the modular reduction is also done for the multiplicities
of the factors. Is this a bug or am I making a mistaking in using reduce?

Best regards
Michael
