Lower and upper solutions for general two-point fractional order boundary value problems
(Işık University Press, 2015)This paper establishes the existence of a positive solution of fractional order two-point boundary value problem, Dq1a+ y(t) + f(t, y(t)) = 0, t ? [a, b], y(a) = 0, y?(a) = 0, ?Dq2a+ y(b) ? ?Dq3a+ y(a) = 0, where Dqia+ , ... -
Graphs with equal domination and independent domination number
(Işık University Press, 2015)A set S of vertices of a graph G is an independent dominating set of G if S is an independent set and every vertex not in S is adjacent to a vertex in S. The independent domination number of G, denoted by i(G), is the ... -
Weak convergence theorem for the ergodic distribution of a random walk with normal distributed interference of chance
(Işık University Press, 2015)In this study, a semi-Markovian random walk process (X(t)) with a discrete interference of chance is investigated. Here, it is assumed that the ?n, n = 1, 2, 3, ..., which describe the discrete interference of chance are ... -
Derivative free multilevel optimization
(Işık University Press, 2015)Optimization problems with different levels arise by discretization of ordinary and partial differential equations. We present a trust-region based derivative-free multilevel optimization algorithm. The performance of the ... -
Generalized intuitionistic fuzzy laplace transform and its application in electrical circuit
(Işık University Press, 2015)In this paper we describe the generalized intuitionistic fuzzy laplace transform method for solving first order generalized intutionistic fuzzy differential equation. The procedure is applied in imprecise electrical circuit ... -
An algorithm for solving fuzzy relation programming with the max-t composition operator
(Işık University Press, 2015)This paper studies the problem of minimizing a linear objective function subject to max-T fuzzy relation equation constraints where T is a special class of pseudot-norms. Some sufficient conditions are presented for ... -
Common fixed point theorems for finite number of mappings in symmetric spaces
(Işık University Press, 2015)In this paper, we prove a common fixed theorem for ten mappings on symmetric spaces. We extend our result for finite number of mappings. The mappings involved in our results are noncompatible and discontinuous. We extend ... -
On generalized phi-recurrent kenmotsu manifolds
(Işık University Press, 2015)The aim of the present paper is to study the properties of generalized ??recurrent and concircular ??recurrent Kenmotsu manifolds. -
Fixed points on T0-QPMS
(Işık University Press, 2014-05-05)In this paper, we proved some fixed point results for maps in quasi-pseudometric spaces. The theorems are a generalization of the results presented in [3]. -
A mathematical model on genetic dihybrid and multihybrid
(Işık University Press, 2014-04-05)Human and, in fact, every animal or plant contains many gene oriented traits. This means that the traits depend on chromosomes and are mainly directed by DNA sequence. On the other hand, a particular trait of any species ... -
On controlled poisson processes
(Işık University Press, 2014)We consider a special class of two-dimensional Markov processes, finding the relationship between transition probabilities of two such classes. -
Analysis of discrete-time queue with two heterogeneous servers subject to catastrophes
(Işık University Press, 2014)This paper studies a discrete-time queueing system with two heterogeneous servers subject to catastrophes. We obtain explicit expressions for the steady-state probabilities at arbitrary epoch using displacement operator ... -
Multiple sequences in cone metric spaces
(Işık University Press, 2014-03-03)In this study, we introduce the ordinary and statistical convergence of double and multiple sequences in cone metric spaces. Moreover, the relationships between these convergence types are also invastigated. -
Partial complete controllability of deterministic semilinear systems
(Işık University Press, 2014-03-03)In this paper the concept of partial complete controllability for deterministic semilinear control systems in separable Hilbert spaces is investigated. Some important systems can be expressed as a first order differential ... -
Remotality of certain sets Lp(I,X)
(Işık University Press, 2014)Let X be a Banach space and let (I, ?, µ) be a measure space. For 1 ? p < ?, let Lp (I, X) denote the space of Bochner p?integrable functions defined on I with values in X. The object of this paper is to give sufficient ... -
Solution of two-dimensional heat and mass transfer equation with power-law temperature-dependent thermal conductivity
(Işık University Press, 2014-01-31)In this paper, we obtain the particular exact solutions of the two-dimensional heat and mass transfer equation with power-law temperature-dependent thermal conductivity using the Adomian’s decomposition method. In comparison ... -
"Yarman-36 makam tone-system" for Turkish art music
(Işık University Press, 2014)This study offers a mathematically rigorous, yet straightforward, fixed-pitch tuning strategy to the problem of adequate sounding and notating of essential Turkish makam genera, in contradistinction to the praxis-mismatched ... -
Fixed points of contractive set valued mappings with set valued domains on a metric space with graph
(Işık University Press, 2014)In this article we consider general contractive mappings of the form F : CB(X) ? CB(X), where CB(X) is the set of all nonempty closed and bounded subsets of a complete metric space X endowed with a graph G. We prove some ... -
Solving fractional diffusion and fractional diffusion-wave equations by Petrov-Galerkin finite element method
(Işık University Press, 2014)In the last few years, it has become highly evident that fractional calculus has been widely used in several areas of science. Because of this fact, their numerical solutions also have become urgently important. In this ... -
On trigonometric approximation in the space lp(x)
(Işık University Press, 2014)In this paper we have introduced two new class of numerical sequences, named almost monotone decreasing (increasing) upper second mean sequences. Moreover, we have presented some results on trigonometric approximation of ...
