Toward Berenstein-Zelevinsky data in affine type , I: Construction of affine analogs
arXiv:1009.4526
Abstract
We give (conjectural) analogs of Berenstein-Zelevinsky data for affine type . Moreover, by using these affine analogs of Berenstein-Zelevinsky data, we realize the crystal basis of the negative part of the quantized universal enveloping algebra of the (Langlands dual) Lie algebra of affine type .
