Article Alternative Variational Iteration Method for Solving the Time-Fractional Fornberg-Whitham Equation(Elsevier Science inc, 2015) Sakar, Mehmet Giyas; Ergoren, HilmiIn this study, we apply an alternative variational iteration method to solve the time-fractional Fomberg-Whitham equation. A comparison between the results obtained using the alternative variational iteration method and known results obtained with the variational iteration method demonstrates that the proposed method is highly effective and convenient. The fractional derivatives are described in the Caputo sense. Numerical results are presented for different specific cases of the problem. (C) 2014 Elsevier Inc.

What is more, it shows that all the solutions are in L-p[0,infinity) Under somewhat more restrictive conditions.Conference Object On the Positive Solutions for Fractional Differential Equations With Weakly Contractive Mappings(Amer inst Physics, 2015) Ergoren, HilmiThis work aims to show the existence and uniqueness of positive solutions of a class of fractional differential equations subject to hybrid boundary conditions by using some fixed point theorems via weakly contractive maps in view of partially ordered sets.Article Some Existence Results for Impulsive Nonlinear Fractional Differential Equations With Closed Boundary Conditions(Hindawi Ltd, 2012) Ergoren, Hilmi; Kilicman, AdemWe investigate some existence results for the solutions to impulsive fractional differential equations having closed boundary conditions. Our results are based on contracting mapping principle and Burton-Kirk fixed point theorem.
