Relative C?-simplicity and characterizations for normal subgroups
نویسندگان
چکیده
The notion of a plump subgroup was recently introduced by Amrutam. This is relativized version Powers' averaging property, and it known that property equivalent to C*-simplicity. With this in mind, we introduce C*-simplicity, show for normal subgroups plumpness, along with several other characterizations.

On c-normal and hypercentrally embeded subgroups of finite groups∗
In this article, we investigate the structure of a finite group G under the assumption that some subgroups of G are c-normal in G. The main theorem is as follows: Theorem A. Let E be a normal finite group of G. If all subgroups of Ep with order dp and 2dp (if p = 2 and Ep is not an abelian nor quaternion free 2-group) are c-normal in G, then E is p-hypercyclically embedded in G. We give some ap...

متن کاملCharacterizations of Multivariate Normal-Poisson Model
‎Multivariate normal-Poisson model has been recently introduced as a special case of normal stable Tweedie models‎. ‎The model is composed of a univariate Poisson variable‎, ‎and the remaining variables given the Poisson one are independent Gaussian variables with variance the value of the Poisson component‎. ‎Two characterizations of this model are shown‎, ‎...
