The condition $([\omega],\beta)=0$ is introduced for convenience only. It helps to avoid the problem with the composition $m_{0}$ we mentioned before. The condition holds in the case when $V$ is a torus with the constant symplectic form, and $L$ is a Lagrangian subtorus. This is our main application in present paper. In general there is a way to work with non-trivial $m_{0}$, if it is small in the adic topology.
