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.

正常域上的梯形行列式环

摘要

我们明确地描述了梯形行列式环的除数类组和半对偶化模块，其中系数在任意正则域（不一定是相连的）的任意正态域中以及所有大小的未成年人中。
