Finding the traveling wave solutions of some nonlinear partial differential equations by an expansion method
(İstanbul Ticaret Üniversitesi, 2016)In this study, we construct an expansion method. We have implement this method for finding traveling wave solutions of nonlinear KleinGordon equation, BenjaminBonaMahony equation, sixthorder Boussinesq equation and ... 
Traveling wave solutions of some nonlinear partial differential equations by using extended  expansion method
(İstanbul Ticaret Üniversitesi, 2015)In this study, we use extended (G’/G)expansion method which is suggested in (Wang et al., 2008). By this method, we find traveling wave solutions of nonlinear Burgers and KdV equations. It is obtained graphics of these ...

(Springer International Publishing AG, 2008)We study the notion of (lambda) over bar statistically convergent for double sequence of fuzzy numbers and also get some inclusion relations. Copyright (C) 2008 Ekrem Savas. 
On the cesaro summability of double series
(Springer International Publishing AG, 2008)In a recent paper by Savas, and Sevli (2007), it was shown that each Cesaro matrix of order alpha, for alpha > 1, is absolutely kth power conservative for k >= 1. In this paper we extend this result to double Cesaro ...
