This paper provides a construction of the Drinfeld coproduct on an affine quantum Kac–Moody algebra or on a quantum affinization through the exponentials of some locally nilpotent derivations, thus proving that this “coproduct” with values in a suitable completion of U ⊗ U is well defined.

Abstract
This paper provides a construction of the Drinfeld coproduct on an affine quantum Kac–Moody algebra or on a quantum affinization through the exponentials of some locally nilpotent derivations, thus proving that this “coproduct” with values in a suitable completion of U ⊗ U is well defined.File in questo prodotto:
