Common fixed point of g-approximative multivalued mapping in partially ordered metric space
(Univ Nis, Fac Sci Math, 2013)In this paper, we introduce g-approximative multivalued mappings. Based on this definition, we gave some new definitions. Further, common fixed point results for g-approximative multivalued mappings satisfying generalized ... -
Kantrovich Type Generalization of Meyer-Konig and Zeller Operators via Generating Functions
(Ovidius Univ Press, 2013)In the present paper, we study a Kantorovich type generalization of Meyer-Konig and Zeller type operators via generating functions. Using Korovkin type theorem we first give approximation properties of these operators ... -
An Extension of Some Lauricella Hypergeometric Functions
(Amer Inst Physics, 2013)In this paper, we present an extension of Lauricella hypergeometric functions, which is motivated by the extended Beta function. -
A fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type
(Charles Babbage Res Ctr, 2013)In this paper, we prove a fixed point theorem for weakly compatible mappings satisfying a general contractive condition of operator type. In short, we are going to study mappings A, B,S,T : X -> X for which there exists a ... -
Common fixed point theorems on non-complete partial metric spaces
(Inst Mathematics & Informatics, 2013)In the peresent paper, we give a common fixed point theorem for four weakly compatible mappings on non-complete partial metric spaces. Some supporting examples are provided. -
Some fixed point theorems for maps with fuzzy distance in uniform space
(Springer, 2013)The purpose of this paper is to define the notion of fuzzy A-distance in uniform spaces and give several new common fixed point results for weakly compatible contractive or expansive selfmappings on uniform spaces. -

(Hacettepe Univ, Fac Sci, 2013)Fixed point and common fixed point results for generlized contractive mappings are obtianed in ordered cone metric spaces. -
Some new generalizations of Mizoguchi-Takahashi type fixed point theorem
(Springer International Publishing Ag, 2013)In the light of the paper of Hasanzade Asl et al. (Fixed Point Theory Appl. 2012: 212, 2012, doi:10.1186/1687-1812-2012-212), we obtain a fixed point theorem for multivalued mappings on a complete metric space. Our result ... -
Some new iterated Hardy-type inequalities: the case θ=1
(Springer International Publishing Ag, 2013)In this paper we characterize the validity of the Hardy-type inequality parallel to parallel to integral(infinity)(s)h(z)dz parallel to(p,u,(0,t))parallel to(q,w,(0,infinity)) <= c parallel to h parallel to(1,v,(0,infinity)), ... -
On the q analogue of Stancu-Beta operators
(Pergamon-Elsevier Science Ltd, 2012)In the present work we introduce the q analogue of well known Stancu-Beta operators. We estimate moments and establish direct results in terms of the modulus of continuity. We also present an asymptotic formula. (C) 2011 ... -
Some characterizations of null osculating curves in the Minkowski space-time
(Estonian Academy Publishers, 2012)In this paper we give the necessary and sufficient conditions for null curves in E-1(4), to be osculating curves in terms of their curvature functions. In particular, we obtain some relations between null normal curves and ... -
Some Generalized Fibonomial Sums related with the Gaussian q-Binomial sums
(Soc Matematice Romania, 2012)In this paper, we consider some generalized Fibonomial sums formulae and then prove them by using the Cauchy binomial theorem and q-Zeilberger algorithm in Mathematica session. -
Some properties of the multivariate százs operators
(Publ House Bulgarian Acad Sci, 2012)In this work some properties of multivariate Szazs operators are considered. We prove that the Szazs operators preserve some properties of the function of modulus of continuity, Lipschitz condition, and a kind of monotonicity. -

Analysis of Thermal Environmental Effects on Precast, Prestressed Concrete Bridge Girders: Temperature Differentials and Thermal Deformations
(Multi-Science Publ Co Ltd, 2012)AASHTO specifications provide vertical thermal gradients for the thermal design of precast, prestressed concrete bridge girders. However, the thermal behavior of the girders pertains to not only vertical thermal movement ... -
Fixed point theorems for a pair of mappings satisfying a generalized weakly contractive condition in ordered metric spaces
(Hacettepe Univ, Fac Sci, 2012)Fixed point theorems for a pair of mappings which satisfy the condition of being generalized weakly contractive in complete ordered metric spaces are derived. At the end of the paper, applications of the previous results ... -
Common fixed point of mappings satisfying almost generalized (S,T)-contractive condition in partially ordered partial metric spaces
