A Fixed point theorem on cone metric spaces with new type contractivity
Altun, Ishak; Abbas, Mujahid; Simsek, Hakan (Duke Univ Press, 2011)In the present work, a common fixed point theorem for self maps on cone metric spaces is proved. Also two examples, which shows that our main theorem is generalized version of main theorems of [A. Branciari, Int. J. Math. ... -
Fixed Point Theorems on Complete Quasi Metric Spaces Via C-class and A-Class Functions
Yalcin, M. Tugba; Simsek, Hakan; Altun, Ishak (UNIV MARAGHEH, 2020)In this paper, we present some fixed point theorems for single valued mappings on K-complete, M-complete and Symth complete quasi metric spaces. Here, for contractive condition, we consider some altering distance functions ... -
Generalized contractions on partial metric spaces
Altun, Ishak; Sola, Ferhan; Simsek, Hakan (Elsevier Science Bv, 2010)In the present paper, we give some fixed point theorems for generalized contractive type mappings on partial metric space. Also, a homotopy result is given. (C) 2010 Elsevier B.V. All rights reserved. -
Generalized Z-contraction on quasi metric spaces and a fixed point result
Simsek, Hakan; Yalcin, Mensur Tugba (Int Scientific Research Publications, 2017)The simulation function is defined by Khojasteh et al. [F. Khojasteh, S. Shukla, S. Radenovic, Filomat, 29 (2015), 1189-1194]. Khojasteh introduced the notion of Z-contraction which is a new type of nonlinear contractions ... -
Some Fixed Point Theorems on Ordered Metric Spaces and Application
Altun, Ishak; Simsek, Hakan (Springer International Publishing Ag, 2010)We present some fixed point results for nondecreasing and weakly increasing operators in a partially ordered metric space using implicit relations. Also we give an existence theorem for common solution of two integral equations. -
Two type quasi-contractions on quasi metric spaces and some fixed point results
Simsek, Hakan; Altun, Ishak (Int Scientific Research Publications, 2017)In this paper, we introduce new concepts of quasi-contractions of type (A) and of type (B) in a quasi metric space and we present the differences between of them. Then we present some fixed point results. In the light of ...
