The cotorsion pair generated by the Gorenstein projective modules and $\lambda$-pure-injective modules

Manuel Cortés-Izurdiaga, Jan Šaroch

We prove that, if $\text{GProj}$ is the class of all Gorenstein projective modules over a ring $R$, then $\mathfrak{GP}=(\text{GProj},{\text{GProj}}^{\perp })$ is a cotorsion pair…
