On rings related to filial and left filial rings

DIC Mendes - Quaestiones Mathematicae, 2022 - Taylor & Francis
A ring R is called filial (left weakly filial) if it satisfies the following condition: for all subrings J
and I of R, if J is an ideal of I and I is an ideal of R, then J is an ideal (left ideal) of R. If every …
