B.7.0.7 Heisenberg
Procedure from library nctools.lib (see nctools_lib).
- Return:
- N-th Heisenberg algebra in x(i),y(i),h realization
- Note:
- you have to activate this ring with the "setring" command
Example:
| LIB "nctools.lib";
def a = Heisenberg(2);
setring a;
a;
==> // characteristic : 0
==> // number of vars : 5
==> // block 1 : ordering lp
==> // : names x(1) x(2) y(1) y(2) h
==> // block 2 : ordering C
==> // noncommutative relations:
==> // y(1)x(1)=x(1)*y(1)+h
==> // y(2)x(2)=x(2)*y(2)+h
