  Using the operator formulation we discuss the bosonization of the
two-dimensional derivative-coupling model. The fully bosonized quantum
Hamiltonian is obtained by computing the composite operators as the leading
terms in the Wilson short distance expansion for the operator products at the
same point. In addition, the quantum Hamiltonian contains topological terms
which give trivial contributions to the equations of motion. Taking into
account the quantum corrections to the bosonic equations of motion and to the
scale dimension of the Fermi field operator, the operator solution is obtained
in terms of a generalized Mandelstam soliton operator with continuous Lorentz
spin (generalized statistics).
