RESUMO

Using the order-disorder formalism we obtain the explicit form or the soliton operator of the Gross-Neveu model and we calculate, in a particuar aproximation, the two point correlation function of these operators. From the asymptotic behaviour of this function we obtain the soliton mass. As a by-product we calculate the fermionic determinant. ( i¶ - m + aA ) for a peculiar field configuration Am
