Abstract: In this study, we have applied the generalized kudryashov method to the symmetric regularized long wave equation for obtaining some new analytical solutions such as trigonometric function solution, exponential function solution, complexl function solution, hyperbolic function solution after giving the fundamental properties of method. Afterwards, we have observed that these analytical solutions are verified the symmetric regularized long wave equation by means of Wolfram Mathematica 9. Then, we have drawn two and three dimensional surfaces of analytical solutions. Finally, we have submitted a conclusion to literature.

1. Introduction

All over the world, some researchers have submitted to literature some analytical solutions of many nonlinear partial differential equations. Many powerful methods such as the transformation techniques, the sine–cosine technique, the exponential function method, the standard tanh and developed tanh methods, the jacobi function method, trial equation method, darboux transformation, homotopy perturbation method, sumudu transform method, kudryashov method and so on have been applied successfully [1-11].

When it comes to this paper, we have presented the general properties of generalized kudryashov method (GKM) [12] in section 2. In section 3, we have applied GKM to the symmetric regularized long wave equation (SRLW) defined by [13]

(1.1)

Finally, we have submitted a conclusion including some important remarks in section 4.

2. General Properties of Generalized Kudryashov Method

Recently, some authors have constructed the generalized kudryashov method [12]. We consider the following nonlinear partial differential equation for a function of two real variables, space and time:

(2.1)

The basic phases of the generalized kudryashov method are expressed as the follows:

Step 1. First of all, we must get the travelling wave solution of Eq.(2.1) as following form;

(2.2)

whereand are arbitrary constants. Eq.(2.1) was converted into a nonlinear ordinary differential equation of the form:

(2.3)

where the prime indicates differentiation with respect to

Step 2. Suggest that the exact solutions of Eq.(2.3) can be written as the following form;

(2.4)

where is. We note that the function  is solution of equation [12]

(2.5)

Taking into consideration Eq.(2.4), we obtain

(2.6)

(2.7)

(2.8)

Step 3. Under the terms of proposed method, we suppose that the solution of Eq.(2.3) can be explained in the form of the following:

(2.9)

To calculate the values and  in Eq.(2.9) that is the pole order for the general solution of Eq.(2.3), we progress conformably as in the classical kudryashov method on balancing the highest order nonlinear terms in Eq.(2.3) and we  can determine a formula of and . We can receive some values of and .

Step 4. Replacing Eq.(2.4) into Eq.(2.3) provides a polynomialof. Establishing the coefficients of to zero, we acquire a system of algebraic equations. Solving this system, we can describe and the variable coefficients of. In this way, we attain the exact solutions to Eq.(2.3).

3. Implementation of Method Proposed

For symmetric regularized long wave equation [13]

(3.1)

with Eq.(2.2) transformation, nonlinear differential form for Eq.(3.1) is obtained as the following;

(3.2)

andterms is used according to balance principle. And then, balance term is obtained as the following;

(3.3)

Case 1: Forand when Eq.(2.7) is rewritten with Eq.(2.4), we can find follows;

4. Conclusions

In this paper, symmetric regularized long wave equation has been solved by using GKM. We have obtained the prototype solutions such as complex function, trigonometric function, exponential function and hyperbolic function solutions. It has been observed that these analytical solutions have verified to the SRLW Eq.(1.1) by using Wolfram Mathematica 9.

These analytical solutions obtained by using GKM in this paper are new complex, trigonometric, exponential and hyperbolic function solutions when we compare these solutions with analytical solutions obtained by Jalil Manafian and Isa Zamanpour [13]. Then, two and three dimensional surfaces of these analytical solutions have been plotted by using Wolfram Mathematica 9.

According to solutions and graphics, one can see that GKM is a powerful tool for obtaining some new analytical solutions for such problems.
