Abstract

We prove the analogue of Weyl's law for a noncommutative Riemannian manifold, namely the noncommutative two torus Tθ2\mathbb{T}_\theta^2 equipped with a general translation invariant conformal structure and a Weyl conformal factor. This is achieved by studying the asymptotic distribution of the eigenvalues of the perturbed Laplacian on Tθ2\mathbb{T}_\theta^2. We also prove the analogue of Connes' trace theorem by showing that the Dixmier trace and a noncommutative residue coincide on pseudodifferential operators of order -2 on Tθ2\mathbb{T}_\theta^2.
