Let (E,???) be a Banach space with a cone P. Let T,?i : E ? E (i = 1,2,...,r) be a finite number of mappings. We obtain sufficient conditions for the existence of solutions to the problem {(Tx = x, ?i(x)=0E, i=1,2,..., r, where 0E is the zero vector of E, and T is a mapping satisfying a Ciric-contraction. Some interesting consequences are deduced from our main results.
