We prove that the constant term of the Laurent polynomial @?"1" =<"i"<"j"=<"n(x"i/x"j)"a"""i(qx" j/ x"i)" a"""j, where x"1,...,x"n,q are commuting indeterminates and a" 1,...,a"n are non-negative integers.Expand

This is an exposition and elaboration on work of W.H. Burge which demonstrates the connections among the various combinatorial interpretations of the multiple summations which arise in… Expand
