设是一个半单环,它的中心。假设对于任何素数理想,环都是素数的。设为、和的极大环的交集。我们证明了有有限个不可分解的积分表示当且仅当是遗传环,有两个生成元作为模,并且是循环的。
Let be a semisimple -ring and its center. Assume that for any prime ideal the ring is primary. Let be the intersection of the maximal over-rings of , and . We prove that has a finite number of indecomposable integral representations if and only if is a hereditary ring, has two generators as a -module, and is cyclic.
