Abstract
In this paper, the removability of the Hopf term in the 2+1D CP1 model is studied. A quantum unitary transformation is found and used to rem ove the Hopf term from the Hamiltonian for the model. It is then shown that there is an intimate connection between the Hopf term and the mu ltivaluedness of the wavefunctional describing the model.
