Fixed point results of expanding mapping in the abstract space with nonsolid cone
This paper established theories about fixed-point results of expanding mapping in the abstract metric spaces with a nonsolid cone and redefied Cauchy sequences,convergent sequences and completeness in cone metric spaces over Banach algebras.It proved the uniqueness of the fixed points in the nonsolid abstract spaces by deleting the continuity assumption,and the main results extended several interesting theorems in cone metric spaces and metric spaces.
