  An application of the equation proposed by the present authors, which is
equivalent to the static field equation of the Faddeev model, is discussed.
Under some assumptions on the space and on the form of the solution, the field
equation is reduced to a non-linear ODE of second order. By solving this
equation numerically, some solitonic solutions are obtained. It is discussed
that the product of two integers specifying solutions may be identified with
the Hopf topological invariant.
