This is a key for a LieAlgebra L, giving the differential of the generators. It can be seen by applying peekLie to L. The value is also the input for diffLieAlgebra. Observe that if the value is defined by L.genDiffs = {...}, then no checking of correctness of input is made. For that reason, use diffLieAlgebra instead.
i1 : L=lieAlgebra({a,b,c},genWeights=>{{2,0},{2,1},{4,2}},genSigns=>{0,1,0},diffl=>true) o1 = L o1 : LieAlgebra |
i2 : L=diffLieAlgebra{L.zz,a,a b}/{c b,a c-b a b} o2 = L o2 : LieAlgebra |
i3 : L.genDiffs o3 = {0, a, - (b a)} o3 : List |
