Let T be a Krull–Schmidt, Hom-finite triangulated category with suspension functor [1]. Let R be a basic rigid object, Γ the endomorphism algebra of R, and pr (R)⊆ T the subcategory of objects finitely presented by R. We investigate the relative rigid objects, ie R [1]-rigid objects of T. Our main results show that the R [1]-rigid objects in pr (R) are in bijection with τ-rigid Γ-modules, and the maximal R [1]-rigid objects with respect to pr (R) are in bijection with support τ-tilting Γ-modules. We also show that various previously known bijections involving support τ-tilting modules are recovered under respective assumptions.
