## Notes

1 | We say that a closed convex set $\mathcal{C}$ is a convex cone if for every point $x\in \mathcal{C}$ all points of the form $\lambda x$ where $\lambda $ is positive also belong to $\mathcal{C}.$ Notice that in our terminology a vector space is a convex cone. |

3 | Notice that (16) and (17) can be considered either as an inclusive scattering matrix of elementary excitations of state $\omega $ or as an inclusive scattering matrix of elementary excitations of state $\alpha $. A similar statement is true for analogs of green functions introduced in Section 6. It is not clear whether this strange duality has any physical meaning. |
