Abstract:
We study the $t$-structure induced by an $n$-tilting module $T$ in the derived category $\mathcal {D}(R)$ of a ring $R$. Our main objective is to determine when the heart of the $t$-structure is a Grothendieck category. We obtain characterizations in terms of properties of the module category over the endomorphism ring of $T$ and, as a main result, we prove that the heart is a Grothendieck category if and only if $T$ is a pure projective $R$-module.References
