Abstract

Let (M,J,ω)(M,J,\omega) be a quantizable compact K\"ahler manifold, with quantizing Hermitian line bundle (A,h)(A,h), and associated Hardy space H(X)H(X), where XX is the unit circle bundle. Given a collection of rr Poisson commuting quantizable Hamiltonian functions fjf_j on MM, there is an induced Abelian unitary action on H(X)H(X), generated by certain T\"oplitz operators naturally induced by the fjf_j's. As a multi-dimensional analogue of the usual Weyl law and trace formula, we consider the problem of describing the asymptotic clustering of the joint eigenvalues of these T\"oplitz operators along a given ray, and locally on MM the asymptotic concentration of the corresponding joint eigenfunctions. This problem naturally leads to a \lq directional local trace formula\rq, involving scaling asymptotics in the neighborhood of certain special loci in MM. Under natural transversality assumption, we obtain asymptotic expansions related to the local geometry of the Hamiltonian action and flow.
