Abstract
In this article we introduce and investigate a particular class of n-perfect rings that we call “strong n-perfect rings.” We are mainly concerned with this class of rings in the context of pullbacks. We also exhibit a class of n-perfect rings that are not strong n-perfect. Finally, we establish the transfer of this notion to the direct product.
