A semitoric system is an integrable system $F=(J,H)$, with semiclassical joint spectrum given by the points $(\lambda,\nu)\in\mathbb R^2$ where $\lambda$ is an eigenvalue of…

Let $\hat{J}$ and $\hat{H}$ be the semiclassical Toeplitz operators associated with a semitoric system near a focus-focus singularity. The singular Bohr–Sommerfeld formula describe…
