Abstract:
The structure of the kernel of a canonical transformation and a
differential equation for the symbol of the intertwining operator
are found. The symbol of a general linear canonical transformation
is constructed in terms of a Cayley transformation of the
symplectic transformation of the phase space. Its singularities
and applications to group theory are studied. The Green's
functions and spectral projectors of arbitrary quadratic systems
are constructed using the classification methods of classical
mechanics.
