  • Fixed points of generalized contraction mappings in cone metric spaces 
    Türkoğlu, Duran; Abuloha, Muhib; Abdeljawad, Thabet (Univ Osijek, Depth Mathematics, 2011-12)
    In this paper, we proved a fixed point theorem and a common fixed point theorem in cone metric spaces for generalized contraction mappings where some of the main results of Ciric in [8, 27] are recovered.
  • KKM mappings in cone metric spaces and some fixed point theorems 
    Türkoğlu, Duran; Abuloha, Muhib; Abdeljawad, Thabet (Pergamon-Elsevier Science, 2010-01-01)
    In this paper, we define KKM mappings in cone metric spaces and define NR-cone metric spaces to obtain some fixed point theorems and hence generalize the results obtained in [A. Amini, M. Fakhar, J. Zafarani, KKM mapping ...
  • Locally convex valued rectangular metric spaces and the kannan's fixed point theorem 
    Abdeljawad, Thabet; Türkoğlu, Duran (Eudoxus Press, 2012-04)
    Rectangular TVS-cone metric spaces are introduced and Kannan's fixed point theorem is proved in these spaces. Two approaches are followed for the proof. At first we prove the theorem by a direct method using the structure ...
  • Some Theorems and Examples of Cone Banach Spaces 
    Abdeljawad, Thabet; Türkoğlu, Duran; Abuloha, Muhib (Eudoxus Press, 2010-10)
    In this paper, by defining a cone norm parallel to.parallel to(A) on E over itself which behaves like the absolute value norm on R, we construct examples of cone Banach spaces. Namely, we define the m-Euclidian cone normed ...
