On properties of the nonlinear Schroedinger equation with U(p,q) internal symmetry
Description
The nonlinear Schroedinger equation in a two-dimensional space-time with a noncompact group of internal symmetry U(p, q) (p+q-n) is studied. It is shown to be Hamiltonian. The linear (n+1)x(n+1) matrix problem corresponding to this equation has been found. n2 conserving local currents out of which the isotopic group generators are constructed, have been found. Its properties are discussed
