Almost Picard Operators
Altun, Ishak; Hancer, Hatice Aslan (Amer Inst Physics, 2019)The concept of Picard operator is one of the most important concept of fixed point theory. As known, a self mapping T of a metric space X is called Picard operator (PO) if it has unique fixed point and every Picard iteration ... -
Fixed point results for single valued and set valued P-contractions and application to second order boundary value problems
Altun, Ishak; Hancer, Hatice Aslan; Erduran, Ali (NORTH UNIV BAIA MARE, 2020)In this paper, by considering the concept of set-valued nonlinear P-contraction which is newly introduced, we present some new fixed point theorems for set-valued mappings on complete metric space. Then by considering a ... -
On A Broad Category Of Multivalued Weakly Picard Operators
Hancer, Hatice Aslan; Minak, Gulhan; Altun, Ishak (House Book Science-Casa Cartii Stiinta, 2017)In the present paper, considering a recent technique which is used by Jleli and Samet [10] for fixed points of single-valued maps, we introduce a new concept of multivalued theta-contractions on metric spaces and prove ... -
On two types almost (α,F_{d})-contractions on quasi metric space
Hancer, Hatice Aslan (Ankara Univ, Fac Sci, 2019)In this paper, first we introduce two new types almost contractions on quasi metric space named as almost (alpha, F-d)-contraction of type (x) and of type (y). Then, taking into account both left and right completeness of ... -
Some new types multivalued F-contractions on quasi metric spaces and their fixed points
Hancer, Hatice Aslan; Olgun, Murat; Altun, Ishak (North Univ Baia Mare, 2019)In this paper we present two new results for the existence of fixed points of multivalued mappings with closed values on quasi metric space. First we introduce the multivalued F-d-contraction on quasi metric space (X, d) ...
