An application of Fibonacci numbers into infinite Toeplitz matrices
2
2
The main purpose of this paper is to define a new regular matrix by
using Fibonacci numbers and to investigate its matrix domain in the
classical sequence spaces $ell _{p},ell _{infty },c$ and $c_{0}$,
where $1leq p

Existence of positive solutions for fourthorder boundary value
problems with three point boundary conditions
2
2
In this work, by employing the Krasnosel'skii fixed point theorem, we study the existence of positive solutions of a threepoint boundary value problem for the following fourthorder differential equation begin{eqnarray*} left { begin{array}{ll} u^{(4)}(t) f(t,u(t),u^{prime prime }(t))=0 hspace{1cm} 0 leq t leq 1, & u(0) = u(1)=0, hspace{1cm} alpha u^{prime prime }(0)  beta u^{prime prime prime }(0)=0, hspace{1cm} u^{prime prime }(1) alpha u^{prime prime }(eta)=0, & end{array} right. end{eqnarray*} where $beta > 0, 0< eta 0$.

0n removable cycles in graphs and digraphs
2
2
In this paper we define the removable cycle that, if $Im$ is a
class of graphs, $Gin Im$, the cycle $C$ in $G$ is called
removable if $GE(C)in Im$. The removable cycles in Eulerian
graphs have been studied. We characterize Eulerian graphs which
contain two edgedisjoint removable cycles, and the necessary and
sufficient conditions for Eulerian graph to have removable cycles
have been introduced. Further, the even and odd removable cycles in
Eulerian graphs have also been studied. The necessary and sufficient
conditions for regular graphs (digraphs) to have a removable cycles
have been characterized. We also define, the removable cycle class.

Differential transformation method for solving a neutral functionaldifferential equation
with proportional delays
2
2
In this article differential transformation method (DTMs) has been used to solve neutral functionaldifferential equations with proportional delays. The method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. Exact solutions can also be obtained from the known forms of the series solutions. The results show that the method is effective, suitable, easy, practical and accurate.

Complexition and solitary wave solutions of the (2+1)dimensional dispersive long wave
equations
2
2
In this paper, the coupled dispersive (2+1)dimensional long wave equation is studied. The traveling wave hypothesis yields complexiton solutions. Subsequently, the wave equation is studied with power law nonlinearity where the ansatz method is applied to yield solitary wave solutions. The constraint conditions for the existence of solitons naturally fall out of the derivation of the soliton solution.
