证明了Dedekind整环的商域上的四元数代数的阶的有限整体维数(fGD)为1。给出了离散赋值环的商域上n × n矩阵的整体维数n-I的阶的例子。
We prove that the finitistic global dimension (fGD) of an order in a quaternion algebra over the quotient field of a Dedekind domain is one. Examples are given of orders of global dimension n-I in n x n matrices over the quotient field of a discrete valuation ring.
