We show that there exist natural q-analogues of the b-functions for the prehomogeneous vector spaces of commutative parabolic type and calculate them explicitly in each case. Our method of calculating the b-functions seems to be new even for the original case q = 1.
After the fundamental theorem for nonregular reductive prehomogeneous vector spaces was proved by A. Gyoja (Tsukuba J. Math. 14 (1990), 437-457), the construction of the theory of nonregular prehomogeneous vector spaces became an interesting problem. However, only Sp n ร GL 2 1 โ 2 1 M 2n 3 is known
