A p-indigent module is one that is subprojective only to projective modules. An RD-
projective module is subprojective to any torsionfree (and flat) module. An RD-projective …

While mutual congeniality of bases is known to guarantee that basic modules from so-
related bases are isomorphic, the question of what can be said about isomorphism of basic …

Given modules X and Y, X is said to be Y-subprojective if for every epimorphism\(\pi:
P\rightarrow Y\) and every homomorphism\(\alpha: X\rightarrow Y\), there exists a …

In this study, we investigate the projectivity domain of pure-projective modules. A pure-
projective module is called special-pure-projective (s-pure-projective) module if its …

In this paper, we introduce an X-precover completing domain X− 1 (L), with L being a class
of modules and not necessarily a single module, and then investigate when every module in …

Propiedades homológicas de los módulos tales como la inyectividad, proyectividad,
planitud, etc. se han considerado clásicamente como atributos que los módulos pueden …

The subjectivity domain of a module allows us to evaluate how close (or far) a module is
from being injective. In this paper, we consider three families of rings characterized by their …

We generalize to exact categories some new perspectives on projectivity, which allow us to
unify a series of recent concepts from module categories or abelian categories and to obtain …
