Macdonald Identities: revisited

K. Iohara, Y. Saito

In this note, after recalling a proof of the Macdonald identities for untwisted affine root systems, we derive the Macdonald identities for twisted affine root systems.

Quantized coordinate rings, PBW-type bases and -boson algebras

Yoshihisa Saito

Recently, Kuniba, Okado and Yamada proved that the transition matrix of PBW-type bases of the positive-half of a quantized universal enveloping algebra coincide…
