On Approximation of General Hamiltonians by Hamiltonians of the Theories of Superconductivity and Susystems if we replace the Kronecker symbol, which expresses the law of conservation of momentum, by several Kronecker symbols, preserving only the terms that contain at least two operators with momenta zero in the interaction Hamiltonian. This list of model systems can be continued.

Index Theorems and Microsupportuch as the index theorem for Toeplitz operators or the relative index theorem for .-modules proved by B. Malgrange and the author. We make a special emphasis on the microlocal contribution produced by the sheaf in which the solutions of the differential equations are computed, as described by P.Scha

Oscillatory Integrals Controlling the Drift of Spectral Projections for Pseudo-Differential Operator that rather explicit formulas for the drift can be found, in such a way that oscillatory integrals involving the symbols will control the variation of the spectral projections. Let’s start now to describe the main features of our approach through a model situation.
