We consider a Krull–Schmidt, Hom-finite, 2-Calabi–Yau triangulated category with a basic rigid objectT, and show a bijection between the set of isomorphism classes of basic rigid objects in the finite presented category prTofTand the set of isomorphism classes of basicτ-rigid pairs in the module category of the endomorphism algebra Endc(T)op. As a consequence, basic maximal objects in prTare one-to-one correspondence to basic supportτ-tilting modules over Endc(T)op. This is a generalization of correspondences established by Adachi–Iyama–Reiten.
