1.Problems of "pushdown" and "pullback" on a commutative ring

交换环上“下降”问题和“上升”问题

2.In this paper, we will give the explicitly condition on the parameter set Ω such that the cyclotomic Birman-Murakami-Wenzl algebra BMWr,2 over a commutative ring is R-free with rank 3r2.

本文将给出关于参数集Ω束条件，使得定义在交换环R上分圆Birman-Murakami-Wenzl代数BMWr，2是秩为3r2自由R-代数.
