Let G be a split semisimple algebraic group over ℚ, g be the Lie algebra of G and U q (g) be the corresponding quantized enveloping algebra. Lusztig has introduced in [Lul] canonical bases for finite-dimensional U q(g)-modules. About the same time E as hi war a introduced in [Kl] crystal bases as a natural framework for parametrizing bases of finite-dimensional U q(g)-modules. It was shown in [Lu2] that Eashiwara’s crystal bases are the limits as q → 0 of Lusztig’s canonical bases. Later, in [K2] Kashiwara introduced a new combinatorial concept — crystals. Kashiwara’s crystals generalize the crystal bases and provide a natural framework for their study.
