论文摘要
我们明确地描述了梯子级组和半虚拟模块的梯子决定性环的模块,该梯子在任意梯子的任意正常域中具有系数,不一定是连接的,以及所有尺寸的未成年人。
We explicitly describe the divisor class groups and semidualizing modules for ladder determinantal rings with coefficients in an arbitrary normal domain for arbitrary ladders, not necessarily connected, and all sizes of minors.
