On the Hochschild (Co)Homology of Quantum Exterior Algebras

We compute the Hochschild cohomology and homology of the algebra Λ = k 〈x, y〉/(x ², xy + qyx, y ²) with coefficients in ₁ Λ_ψ for every degree preserving k-algebra automorphism ψ : Λ → Λ. As a result we obtain several interesting examples of the homological behavior of Λ as a bimodule.
