We perform a comparison between the fractional iteration and decomposition methods applied to the wave equation on Cantorset The operators are taken in the local sense The results illustrate the significant features of the two methods which are both veryeffective and straightforward for solving the differential equations with local fractional derivative

1 Introduction

Many problems of physics and engineering are expressed byordinary and partial differential equations which are termedboundary value problems We can mention for examplethe wave the Laplace the Klein-Gordon the Schrodingerrsquosthe telegraph the Advection the Burgers the KdV theBoussinesq and the Fisher equations and others [1]

Recently the fractional calculus theory was recognized tobe a good tool for modeling complex problems demonstrat-ing its applicability in numerical scientific disciplines Bound-ary value problems for the fractional differential equationshave been the focus of several studies due to their frequentappearance in various areas such as fractional diffusion

and wave [2] fractional telegraph [3] fractional KdV [4]fractional Schrodinger [5] fractional evolution [6] fractionalNavier-Stokes [7] fractionalHeisenberg [8] fractional Klein-Gordon [9] and fractional Fisher equations [10]

Several analytical and numerical techniques were suc-cessfully applied to deal with differential equations frac-tional differential equations and local fractional differentialequations (see eg [1ndash36] and the references therein) Thetechniques include the heat-balance integral [11] the frac-tional Fourier [12] the fractional Laplace transform [12] theharmonic wavelet [13 14] the local fractional Fourier andLaplace transform [15] local fractional variational iteration[16 17] the local fractional decomposition [18] and thegeneralized local fractional Fourier transform [19] methods

2 Abstract and Applied Analysis

Recently the wave equation on Cantor sets (local frac-tional wave equation) was given by [35]

1205972120572119906 (119909 119905)

1205971199052120572minus 1198862120572 1205972120572119906 (119909 119905)

1205971199092120572= 0 (1)

where the operators are local fractional ones [16ndash19 35 36]Following (1) a wave equation on Cantor sets was

proposed as follows [36]

where 119906(119909 119905) is a fractal wave functionIn this paper our purpose is to compare the local

fractional variational iteration and decomposition methodsfor solving the local fractional differential equations Forillustrating the concepts we adopt one example for solving thewave equation on Cantor sets with local fractional operator

Bearing these ideas in mind the paper is organized asfollows In Section 2 we present basic definitions and providesome properties of local fractional derivative and integrationIn Section 3 we introduce the local fractional variationaliteration and the decomposition methods In Section 4 wediscuss one application Finally in Section 5 we outline themain conclusions

2 Mathematical Tools

We recall in this section the notations and some properties ofthe local fractional operators [15ndash19 35 36]

Definition 1 (see [15ndash19 35 36]) The function 119891(119909) is localfractional continuous if it is valid for

1003816100381610038161003816119891 (119909) minus 119891 (1199090)1003816100381610038161003816 lt 120576120572 (3)

where |119909 minus 1199090| lt 120575 for 120576 gt 0 and 120576 isin 119877

We notice that there are existence conditions of localfractional continuities that operating functions are right-hand and left-hand local fractional continuity Meanwhilethe right-hand local fractional continuity is equal to its left-hand local fractional continuity For more details see [35]

Following (4) we have [15ndash19 35 36]

For a fractal set 119865 there is a fractal measure [35]

119867120572(119865 cap (119909 119909

0)) = (119909 minus 119909

0)120572

(5)

where 119891(119909) presents a bi-Lipschitz mapping with fractaldimension 120572 and119867

120572 denotes a Hausdorff dimensionWe verify that there is a measure

1198671(119865 cap (119909 119909

0)) = 119909 minus 119909

0(6)

in the case of 120572 = 1 and 119891(119909) is a Lipschitz mapping If 119865 isa Cantor set we have 119867ln 2 ln 3

(119865 cap (119909 1199090)) = (119909 minus 119909

0)ln 2 ln 3

with 120572 = ln 2 ln 3

Definition 2 (see [15ndash19 35 36]) The local fractional deriva-tive of 119891(119909) at 119909 = 119909

0is defined as [16ndash20]

119891(120572)

(1199090) =

119889120572119891 (119909)

119889119909120572

10038161003816100381610038161003816100381610038161003816119909=1199090

(7)

where

Δ120572(119891 (119909) minus 119891 (119909

0)) cong Γ (1 + 120572) Δ (119891 (119909) minus 119891 (119909

0)) (8)

We find that the existence condition for local fractionalderivative of 119891(119909) is that the right-hand local fractionalderivative is equal to the left-hand local fractional derivative(see eg [16 35] and the references therein)

Definition 3 (see [15ndash19 35 36]) A partition of the interval[119886 119887] is denoted as (119905

119895 119905119895+1

) 119895 = 0 119873 minus 1 1199050= 119886 and

119905119873

= 119887 with Δ119905119895= 119905119895+1

minus 119905119895and Δ119905 = maxΔ119905

0 Δ1199051 Δ119905119895

Local fractional integral of 119891(119909) in the interval [119886 119887] is givenby

If the functions are local fractional continuous then thelocal fractional derivatives and integrals exist That is tosay operating functions have nondifferentiable and fractalproperties (see [35] and the references therein)

Some properties of local fractional derivative and inte-grals are given in [35]

3 Analytical Methods

In order to illustrate two analytical methods we investigatethe nonlinear local fractional equation as follows

119871(119899)

120572119906 + 119877120572119906 = 0 (10)

where 119871(119899)

120572is linear local fractional operators respectively

with 119899 = 1 2 and 119877120572is linear local fractional operators of

order less than 119871(119899)

Abstract and Applied Analysis 3

where 119899is considered as a restricted local fractional varia-

tion that is 120575120572119899= 0 (for more details see [35])

For 119899 = 2 we have

120582120572=

(119904 minus 119905)120572

Γ (1 + 120572) (13)

so that iteration is expressed as

119906119899+1

(119905) = 119906119899(119905) +

Γ (1 + 120572)

120572119906119899(119904) (119889119904)

120572

(14)

Finally the solution is

119906 (119909) = lim119899rarrinfin

119906119899(119909) (15)

32 Local Fractional Decomposition Method When 119871(119899)

120572in

(10) is a local fractional differential operator of order 2120572 wedenote it as

119871(119899)

120572= 119871(2120572)

119909119909=

1205972120572

1205971199092120572

119877120572119906 (119905) =

120597120572

120597119909120572119906 (119905) + 119891 (119905)

(16)

By defining the 119899-fold local fractional integral operator

119871(minus2)

120572119898(119904) =

0119868119909(120572)

0119868119909(120572)

119898(119904) (17)

we get

119871(minus2)

120572119871(2)

120572119906 (119904) = 119871

(minus2)

120572119877120572119906 (119904) (18)

Thus

119906 (119904) = 119903 (119909) + 119871(minus2)

120572119877120572119906 (119904) (19)

where the term 119903(119909) is to be determined from the fractalinitial conditions

Therefore we get the iterative formula as follows

119906 (119909) = 1199060(119909) + 119871

(minus2)

120572119877120572119906 (119904) (20)

with 1199060(119909) = 119903(119909)

Hence for 119899 ge 0 we have the following recurrencerelationship

119906119899+1

(119909) = 119871(minus2)

120572119877120572119906119899(119904)

1199060(119909) = 119903 (119909)

(21)

Finally the solution can be constructed as

119906 (119909) = lim119899rarrinfin

4 An Illustrative Example

In this section one example for wave equation is presented inorder to demonstrate the simplicity and the efficiency of theabove methods

In (2) we consider the following initial and boundaryconditions

120597120572119906 (119909 0)

Γ (1 + 2120572) (23)

Using (14) we have the iterative formula

119906119899+1

(119909 119905)

1205971199092120572= 0 (1)

where the operators are local fractional ones [16ndash19 35 36]Following (1) a wave equation on Cantor sets was

proposed as follows [36]

where 119906(119909 119905) is a fractal wave functionIn this paper our purpose is to compare the local

fractional variational iteration and decomposition methodsfor solving the local fractional differential equations Forillustrating the concepts we adopt one example for solving thewave equation on Cantor sets with local fractional operator

Bearing these ideas in mind the paper is organized asfollows In Section 2 we present basic definitions and providesome properties of local fractional derivative and integrationIn Section 3 we introduce the local fractional variationaliteration and the decomposition methods In Section 4 wediscuss one application Finally in Section 5 we outline themain conclusions

2 Mathematical Tools

We recall in this section the notations and some properties ofthe local fractional operators [15ndash19 35 36]

Definition 1 (see [15ndash19 35 36]) The function 119891(119909) is localfractional continuous if it is valid for

1003816100381610038161003816119891 (119909) minus 119891 (1199090)1003816100381610038161003816 lt 120576120572 (3)

where |119909 minus 1199090| lt 120575 for 120576 gt 0 and 120576 isin 119877

We notice that there are existence conditions of localfractional continuities that operating functions are right-hand and left-hand local fractional continuity Meanwhilethe right-hand local fractional continuity is equal to its left-hand local fractional continuity For more details see [35]

Following (4) we have [15ndash19 35 36]

For a fractal set 119865 there is a fractal measure [35]

119867120572(119865 cap (119909 119909

0)) = (119909 minus 119909

0)120572

(5)

where 119891(119909) presents a bi-Lipschitz mapping with fractaldimension 120572 and119867

120572 denotes a Hausdorff dimensionWe verify that there is a measure

1198671(119865 cap (119909 119909

0)) = 119909 minus 119909

0(6)

in the case of 120572 = 1 and 119891(119909) is a Lipschitz mapping If 119865 isa Cantor set we have 119867ln 2 ln 3

(119865 cap (119909 1199090)) = (119909 minus 119909

0)ln 2 ln 3

with 120572 = ln 2 ln 3

Definition 2 (see [15ndash19 35 36]) The local fractional deriva-tive of 119891(119909) at 119909 = 119909

0is defined as [16ndash20]

119891(120572)

(1199090) =

119889120572119891 (119909)

0)) cong Γ (1 + 120572) Δ (119891 (119909) minus 119891 (119909

0)) (8)

We find that the existence condition for local fractionalderivative of 119891(119909) is that the right-hand local fractionalderivative is equal to the left-hand local fractional derivative(see eg [16 35] and the references therein)

Definition 3 (see [15ndash19 35 36]) A partition of the interval[119886 119887] is denoted as (119905

119895 119905119895+1

) 119895 = 0 119873 minus 1 1199050= 119886 and

119905119873

minus 119905119895and Δ119905 = maxΔ119905

0 Δ1199051 Δ119905119895

Local fractional integral of 119891(119909) in the interval [119886 119887] is givenby

If the functions are local fractional continuous then thelocal fractional derivatives and integrals exist That is tosay operating functions have nondifferentiable and fractalproperties (see [35] and the references therein)

Some properties of local fractional derivative and inte-grals are given in [35]

3 Analytical Methods

In order to illustrate two analytical methods we investigatethe nonlinear local fractional equation as follows

119871(119899)

120572119906 + 119877120572119906 = 0 (10)

where 119871(119899)

120572is linear local fractional operators respectively

with 119899 = 1 2 and 119877120572is linear local fractional operators of

order less than 119871(119899)

120572

31 Local Fractional Variational Iteration Method The localfractional variational iteration algorithm is given by [16 17]on the line of the formalism suggested in [35]
