| Outline of Final Research Achievements |
We have computed b-functions of some reducible prehomogeneous vector spaces by using Lie theory, and have studied properties of b-functions such as relations to group orbits. In addition, we have studied related things as follows. We have clarified combinatorial and representation-theoretic properties of nilpotent orbits on symmetric spaces, and the Lefschetz properties of coinvariant rings of reflection groups.
