摘要
若A是一个Gorenstein代数,则倾斜右A-模的个数等于倾斜左A-模的个数。给出反例说明自内射维数大于等于2的Gorenstein代数B的经典倾斜右B-模的个数不一定等于经典倾斜左B-模的个数。
For a Gorenstein algebra A, the number of tilting right A-modules is equal to the number of tilting left A-modules. A :ounter-example is given to show that for a Gorenstein algebra B with self-injective dimension no less than 2, the number of classical :ilting left B-modules is not necessary to be equal to that of classical tilting right B-modules.
