Abstract:For the Hamiltonian PDEs quantized by a quadratic polynomial with time-dependent coefficients, we give a complete classification for the long-time behaviors of the solution in Sobolev space, through Metaplectic representation and Schrödinger representation. Every behavior of Sobolev norm is characterized by a certain symplectic normal form by means of reducibility.
