TY - JOUR AU - Abou Bakr, Sahar Mohamed Ali PY - 2017 TI - Some Generalized Fixed Point Theorems of Contraction Type Mappings in Quasi Metric Spaces JF - Journal of Mathematics and Statistics VL - 13 IS - 4 DO - 10.3844/jmssp.2017.319.324 UR - https://thescipub.com/abstract/jmssp.2017.319.324 AB - This paper adjusts conditions on new defined given the name {a, d, c; r} ctype of contraction mappings on complete quasi metric space, confirms that there is only one fixed of any of these mappings with these adjustments, extends and generalizes results given in some previous research papers, and then builds a convergence theorem for a sequence of fixed points of {Sn}n∈N;{wn*}n∈N to the unique fixed of S; w, provided that limn→∞  Sn(w) = S(w).
