7.7.12.0. makeQso3
Procedure from library ncalg.lib (see ncalg_lib).
- Usage:
- makeQso3([n]), n an optional int
- Purpose:
- set up the U_q(so_3) in the presentation of Klimyk; if n is specified, the quantum parameter Q will be specialized at the (2n)-th root of unity
- Return:
- ring
- Note:
- activate this ring with the
setring command
Example:
| | LIB "ncalg.lib";
def K = makeQso3(3);
setring K;
K;
==> // coefficients: QQ[Q]/(Q2-Q+1)
==> // number of vars : 3
==> // block 1 : ordering dp
==> // : names x y z
==> // block 2 : ordering C
==> // noncommutative relations:
==> // yx=(Q-1)*xy+(-Q)*z
==> // zx=(-Q)*xz+(-Q+1)*y
==> // zy=(Q-1)*yz+(-Q)*x
