Invariant approximation results via common fixed point theorems for generalized weak contraction maps

Rathee, Savita; Kumar, Anıl; Taş, Kenan (Hindawi Publishing Corporation, 2014)

A common fixed point theorem for generalized (phi,phi,L)(f,g)-weak contraction in a metric space is established. As an application, some common fixed point results in normed linear spaces are obtained. We also study some ...
Nabla discrete fractional Gruss type inequality

Güvenilir, Ayşe Feza; Kaymakçalan, Billur; Peterson, Allan C.; Taş, Kenan (Springer International Publishing, 2014-02-20)

Properties of the discrete fractional calculus in the sense of a backward difference are introduced and developed. Here, we prove a more general version of the Gruss type inequality for the nabla fractional case. An example ...
New common fixed point theorems of gregus type for r-weakly commuting mappings in 2-metric spaces

Murthy, P. P.; Taş, Kenan (Hacettepe Univ, Fac Sci, 2009-12)

In this paper we extend and generalize a theorem of M. R. Singh, L. S. Singh and P. P. Murthy (Common fixed points of set valued mappings, Int. J. Math. Sci., 25 (6), 411-415, 2001) in a 2-metric space with a Gregus type ...
On a fifth-order nonselfadjoint boundary value problem

Uğurlu, Ekin; Taş, Kenan (2021)

In this paper we aim to share a way to impose some nonselfadjoint boundary conditions for the solutions of a formally symmetric fifth-order differential equation. Constructing a dissipative operator related with the problem ...
On coupled fixed point theorems on partially ordered G-metric spaces

Karapınar, Erdal; Kaymakçalan, Billur; Taş, Kenan (Springer International Publishing, 2012)

In this manuscript, we extend, generalize and enrich some recent coupled fixed point theorems in the framework of partially ordered G-metric spaces in a way that is essentially more natural.
On Singular Fifth-Order Boundary Value Problems With Deficiency Indices (5,5)

Uğurlu, Ekin; Taş, Kenan (2022)

This paper is devoted to introduce a way of construction of the well-defined boundary conditions for the solutions of a singular fifth-order equation with deficiency indices (5, 5). Imposing suitable separated and coupled ...
On square integrable solutions of a fractional differential equation

Uğurlu, Ekin; Baleanu, Dumitru; Taş, Kenan (Elsevier Science Bv, 2018-11-15)

In this paper we construct the Weyl-Titchmarsh theory for the fractional Sturm-Liouville equation. For this purpose we used the Caputo and Riemann-Liouville fractional operators having the order is between zero and one.
On sumudu transform method in discrete fractional calculus

Jarad, Fahd; Taş, Kenan (Hindawi Publishing Corporation, 2012)

In this paper, starting from the definition of the Sumudu transform on a general time scale, we define the generalized discrete Sumudu transform and present some of its basic properties. We obtain the discrete Sumudu ...
On the characteristic functions and Dirchlet-integrable solutions of singular left-definite Hamiltonian systems

Bairamov, Elgiz; Taş, Kenan; Uğurlu, Ekin (2024)

In this work, a singular left-definite Hamiltonian system is considered and the characteristic-matrix theory for this Hamiltonian system is constructed. Using the results of this theory we introduce a lower bound for the ...
