NilpotentAlgebraQ
NilpotentAlgebraQ[
L
]
gives
True
if the Lie algebra
L
is nilpotent and
False
otherwise.
MORE INFORMATION
To use
NilpotentAlgebraQ
, you first need to load the
SYM Package
using
Needs
["SYM`"].
The Lie algebra
L
can be provided either from their structure constants or their infinitesimal generator representation.
A Lie algebra
L
is
nilpotent
when the chain of ideals
L
[L, L]
[L, [L, L]]...
terminates to the null set.

In[1]:=
Let the Lie algebra:
In[2]:=
Out[2]=
it is evident from its commutator table that it is solvable
