%0 Journal Article %T The central elements of $E_{q,p}(\hat{sl_2})_k$ with the critical level %A Wenjing Chang %A Xiang-mao Ding %A Ke Wu %J Mathematics %D 2011 %I arXiv %X In this paper we generalize certain results concerning quantum affine algebra $U_{q}(\hat{sl_{2}})$ at the critical level to the corresponding elliptic case $E_{q,p}(\hat{sl_2})$. Using the Wakimoto realization of the algebra $E_{q,p}(\hat{sl_2})$, we construct the central elements of it at the critical level. It turns out that the so called Drinfeld conjecture originally proposed for Kac-Moody algebras also holds for the elliptic quantum algebras. %U http://arxiv.org/abs/1112.2337v1
