NAME: Alexander Berkovich ADDRESS: Department of Mathematics University of Florida 358 Little Hall PO Box 118105 Gainesville FL 32611-8105 EMAIL ADDRESS: alexb@math.ufl.edu TITLE OF TALK: "A double bounded key identity for Goellnitz (big) partition theorem". ABSTRACT OF TALK: Perhaps, one of the deepest results in the theory of partitions is Goellnitz theorem (1967). Recently, Alladi, Andrews and Gordon refined this theorem and showed that it emerges out of, so called, key identity for q-hypergeometric series. In my talk, I, first, give a straight forward interpretation of this identity and then, propose and prove its double bounded terminating analog. This new formula can be viewed as a one parameter extension of the famous Dougall 6 phi 5 summation formula. Finally, I briefly discuss possible ways to go beyond Goellnitz theorem.
