We introduce the τ-Hochschild (co) homology of a finite dimensional associative algebra Λ by means of the higher Auslander-Reiten translate of O. Iyama. We show that the global dimension of Λ, Happel's question and Han's conjecture are related to the τ-Hochschild (co) homology.
Cibils et al. (Fri,) studied this question.
