Abstract

Let T\mathscr T be a 22-Calabi--Yau triangulated category, TT a cluster tilting object with endomorphism algebra Γ\Gamma. Consider the functor T(T,):TmodΓ\mathscr T( T,- ) : \mathscr T \rightarrow \mod \Gamma. It induces a bijection from the isomorphism classes of cluster tilting objects to the isomorphism classes of support τ\tau-tilting pairs. This is due to Adachi, Iyama, and Reiten. The notion of (d+2)( d+2 )-angulated categories is a higher analogue of triangulated categories. We show a higher analogue of the above result, based on the notion of maximal τd\tau_d-rigid pairs.
