Strongly Hopfian Rings of Formal Power Series and Power Series Armendariz Rings in Infinitely Many Variables
摘要
In this paper, we study the strongly Hopfian property in the ring of formal power series in infinitely many variables over chained rings, nonzero characteristic rings and SFT-rings. We investigate the notion of power series Armendariz rings in infinitely many variables and its application to the strongly Hopfian property.
