We define the notion of an infinitely generated tilting object of infinite homologicaldimension in an abelian category. A one-to-one correspondence between ∞-tiltingobjects in complete, cocomplete abelian categories with an injective cogenerator and ∞-cotilting objects incomplete, cocomplete abelian categories with a projective generator is constructed. We also introduce ∞-tilting pairs, consistingof an ∞-tilting objectand its ∞-tiltingclass, and obtain a bijective correspondence between ∞-tilting and ∞-cotiltingpairs. Finally, we discuss the related derived equivalences and t-structures.
