We state the Bohr-Sommerfeld conditions and relate them to the functional calculus of Toeplitz operators, a trace formula and the characteristic classes in deformation quantization. We also develop the symbolic calculus of Lagrangian sections, with the crucial estimate of the subprincipal terms.21 pagesSymplectic GeometrySpectral Theory53D12; 53D50; 53D55; 81S30; 47L80; 35P20text
