Existence and Monotone Iteration of Concave Positive Symmetric Solutions for a Three-Point Second-Order Boundary Value Problems With Integral Boundary Conditions
Akcan, Ummahan; Hamal, Nuket Aykut (Dynamic Publishers, Inc, 2015)In this article, we make use of the monotone iterative technique to verify the existence of concave symmetric positive solutions of a second-order three-point boundary value problem with integral boundary conditions. The ... -
Existence of concave symmetric positive solutions for a three-point boundary value problems
Akcan, Ummahan; Hamal, Nuket Aykut (Springer International Publishing Ag, 2014)In this paper, we investigate the existence of triple concave symmetric positive solutions for the nonlinear boundary value problems with integral boundary conditions. The proof is based upon the Avery and Peterson fixed ... -
GAME CHROMATIC NUMBER OF (WnP2)-P-center dot center dot
Akcan, Ummahan; Akyar, Emrah; Akyar, Handan (Editura Bibliotheca-Bibliotheca Publ House, 2016)In this paper we find an exact value for the game chromatic number of the Cartesian product graph (WnP2)-P-center dot center dot of two graphs, n-wheel W-n and the path graph P-2. This extends a previous work of Sia on the ... -
The Lower and Upper Solution Method for Three-Point Boundary Value Problems with Integral Boundary Conditions on a Half-Line
Akcan, Ummahan; Çetin, Erbil (University Nis, Fac Sci Math, 2018)This paper deal with the following second-order three-point boundary value problem with integral boundary condition on a half-line u ''(x) + q(x) f(x, u(x), u' (x)) = 0, x is an element of(0, +infinity), u(0) = lambda ...
