Summary:
In this paper is studied the equation $(^*)x=Tx+f$ in a complex Banach space $X$, its ordering being given by a normal reproducing cone $K$. Under the assumption that $(^*)$ has exactly one solution in $K$ it is shown that a certain sequence $(w_p)$ (given by iterations - which is an analogue of Marsal's method) converges to $x^*$. The paper is a generalization of Marsal's results.
