I think getting a neat form for the exact order of vanishing is probably complicated, but I haven't thought about it enough (and I'm not an expert). I believe it requires the higher order approximations of group multiplication in exponential coordinates: the Baker-Campbell-Hausdorff formula. | |

BTW, either you simply didn't mean to reuse the same variables A and B in the basis and then again in the commutator relation, or there's something I don't fully understand. So does the theory offer a characterization of words in my $A$ and $B$ that vanish to order k? | |
