Abstract
In the study of the confined classical solutions of the boson form of the massive Thirring field coupled to a Schwinger field, it is observed that, regardless of their respective magnitudes and signs, the Thirring interaction is dominant over the other one, in determining whether such a solution exists. Confined solutions for the Thirring field are possible if and only if the Thirring coupling is attractive. Solutions are constructed for the cases in which the Thirring model coupling is attractive, repulsive, and equal to zero.
