7.7.11.0. makeUso6
Procedure from library ncalg.lib (see ncalg_lib).
- Usage:
- makeUso6([p]); p an optional integer (field characteristic)
- Return:
- a ring, describing U(so_6)
- Note:
- You have to activate this ring with the 'setring' command. The presentation of U(so_6) is derived from the Chevalley representation of so_6, positive resp. negative roots are denoted by x(i) resp. y(i); Cartan elements are denoted by h(i).
Example:
| | LIB "ncalg.lib";
def ncAlgebra = makeUso6();
ncAlgebra;
==> // characteristic : 0
==> // number of vars : 15
==> // block 1 : ordering dp
==> // : names X(1) X(2) X(3) X(4) X(5) X(6) Y(1) Y(2) Y(\
3) Y(4) Y(5) Y(6) H(1) H(2) H(3)
==> // block 2 : ordering C
==> // noncommutative relations: ...
setring ncAlgebra;
// ... 60 noncommutative relations
