Central Extensions of Restricted Affine Nilpotent Lie Algebras $n_{+}(A_1^{(1)})(p)$

Tyler J. Evans, Alice Fialowski

Consider the maximal nilpotent subalgebra $n_{+}(A_1^{(1)})$ of the simplest affine algebra $A_1^{(1)}$ which is one of the $\mathbb{N}$-graded Lie algebras with minimal number of ge…
