Divided Power Integral forms of Affine Algebras
Margherita Paolini
In this paper, we shall prove that the integral subalgebra generated by the divided powers of the Drinfeld generators of an affine Kac-Moody algebra is an integral form. We compare…

On the integral form of rank 1 Kac-Moody algebras
Ilaria Damiani, Margherita Paolini
In this paper we shall prove that the subalgebra generated over the integers by the divided powers of the Drinfeld generators of the Kac-Moody algebra of type $A_2^{(2)…
