When every flat ideal is finitely projective
Tóm tắt
In this paper, we study the class of rings in which every flat ideal is finitely projective. We investigate the stability of this property under localizations and homomorphic images, and its transfer to various contexts of constructions such as direct products, amalgamation of rings
$${A \bowtie^{f} J}$$
, and trivial ring extensions. Our results generate examples which enrich the current literature with new and original families of non-coherent rings that satisfy this property.
