 Post subject: ring parameters
PostPosted: Wed Dec 31, 2008 4:21 pm 
I can not find a description of what a parameter declaration in a ring refers to. as in:
ring r=(23,t,v),(x,a(1..7)),lp;
// the parameters are t,v
what are t,v? are these considered elements in the base ring for symbolic computations?
thanks
A.

In principle yes, see

The parameters may denote transcendental elements or algebraic elements (in case a minimal polynomial is defined).

Best regards,
Alexander
