论文摘要
正如最初由Ashraf和Mozumder定义的那样,乘法(广义)-Skew推导必须满足两个身份。在此简短说明中,我们表明,由于两个身份的同时满足,质子环的多重(广义)-skew推导是乘法(普遍)推导(即,不是偏斜),或者是广义的偏斜衍生(即,加添加剂)。因此,在乘法(广义)-skew推导的定义中,只能采用其中一个身份,以便在Prime Congs中获得一类新的派生。
As originally defined by Ashraf and Mozumder, multiplicative (generalized)-skew derivations must satisfy two identities. In this short note we show that, as a consequence of the simultaneous satisfaction of both identities, a multiplicative (generalized)-skew derivation of a prime ring is either a multiplicative (generalized) derivation (i.e., not skew), or a generalized skew derivation (i.e., additive). Therefore only one of the identities should be taken in the definition of multiplicative (generalized)-skew derivations in order to get a new class of derivations in prime rings.
