B.7.0.15 wRing

Procedure from library nctools.lib (see nctools_lib).

Usage:
see weightedRing

Example:
 
LIB "nctools.lib";
LIB "qmatrix.lib";
def r=quant(2); // generate quant(2) and store it in r
setring r; // set the ring r the active ring
r;
==> //   characteristic : 0
==> //   1 parameter    : q 
==> //   minpoly        : 0
==> //   number of vars : 4
==> //        block   1 : ordering Dp
==> //                  : names    y(1) y(2) y(3) y(4) 
==> //        block   2 : ordering C
==> //   noncommutative relations:
==> //    y(2)y(1)=1/(q)*y(1)*y(2)
==> //    y(3)y(1)=1/(q)*y(1)*y(3)
==> //    y(4)y(1)=y(1)*y(4)+(-q^2+1)/(q)*y(2)*y(3)
==> //    y(4)y(2)=1/(q)*y(2)*y(4)
==> //    y(4)y(3)=1/(q)*y(3)*y(4)
def s=wRing(r);
setring s;
s;

==> //   minpoly        : 0
==> //   number of vars : 4
==> //        block   1 : ordering M
==> //                  : names    y(1) y(2) y(3) y(4) 
==> //                  : weights     2    1    1    1

==> //   noncommutative relations:

==> //    y(3)y(1)=1/(q)*y(1)*y(3)
==> //    y(4)y(1)=y(1)*y(4)+(-q^2+1)/(q)*y(2)*y(3)
==> //    y(4)y(2)=1/(q)*y(2)*y(4)
==> //    y(4)y(3)=1/(q)*y(3)*y(4)
