摘要：
It is shown that the elliptic algebra A(q,p)(<(sl)over cap>(2)(c)) has a non-trivial center at the critical level c = -2, generalizing the result of Reshetikhin and Semenov-Tian-Shansky for trigonometric algebras, A family of Poisson structures indexed by a non-negative integer k is constructed on this center.
