报告摘要：

In this talk, we investigate Auslander-Reiten duality on an exact category $\mathcal{C}$ in terms of morphisms determined by objects. Denote by $\mathcal{C}_l$ the smallest additive subcategory containing injectives and indecomposable objects which appear as the first term of an almost split conflation. We prove that a deflation is right determined by some object if and only if its intrinsic kernel lies in $\mathcal{C}_l$. We give characterizations for $\mathcal{C}$ having Auslander-Reiten duality.

This is a joint work with Professor Jue Le.
