摘要
An explicit expression for the numbers A (n, r; 3) describing the refined 3-enumeration of alternating sign matrices is given. The derivation is based on the recent results of Stroganov for the corresponding generating function. As a result, A(n, r; 3)'s are represented as 1-fold sums which can also be written in terms of terminating F-4(3) series of argument 1/4. (c) 2005 Elsevier Inc. All rights reserved.
