He, that makes no reflexions on what he reads, only loads his mind with a rhapsody of tales fit for the entertainment of others.

A primitive element of a Hopf algebra is an element h∈H such that 𝛥h=1⊗h+h⊗1. It is easily seen that the bracket [x,y]:=xy-yx of two primitive elements is again a primitive element. It follows that primitive elements form a Lie algebra. For H=U(g) any element of g is primitive and in fact using the Poincaré-Birkhoff-Win theorem, one can show that the set of primitive elements of U(g) coincides with the Lie algebra g.

Inland transport of live cod is a far cheaper method than wellboat transport. On the other hand the psychological stress on the fish is much higher and it can by no means be compared with wellboat transport in this field.

I would like to support your proposal, but I can't guarantee how I'll feel down the track.
