Regular Bohr-Sommerfeld quantization rules for a h-pseudo-differential operator. The method of positive commutatorsArticle

Authors: Abdelwaheb Ifa ; Michel Rouleux

    We revisit in this Note the well known Bohr-Sommerfeld quantization rule (BS) for a 1-D Pseudo-differential self-adjoint Hamiltonian within the algebraic and microlocal framework of Helffer and Sjöstrand; BS holds precisely when the Gram matrix consisting of scalar products of some WKB solutions with respect to the " flux norm " is not invertible.
