Nonlinear evolution equations in QCD and effective Hamiltonian at high energy

In this talk I briefly present recent developments in the theory of the Color Glass Condensate. The duality between the dense and dilute regimes of the gluon field is discussed as well as the effective selfdual Hamiltonian which includes both Pomeron merging and Pomeron splitting.Comment: 4 pages.
