1. Introduction

In recent years, a large extent of progress has been made in the differential equation with frequent appearance in physics, chemical and industrial mathematics, processing and control theory, and fluid mechanics. For example, it acquires space-time telegraph fraction equation of the equation classic telegraph by replacing the derivative terms of space-time from the partial derivatives.

The conformable telegraph equations have a wide variety of applications in science and engineering, ideally in optimizing propagation-oriented and propagating electrical communication systems [1, 2]. The solutions obtained from the telegraph equations of fraction of space-time are the terms Mittag-Leffler functions by mixing the Laplace transform and variation iteration method [3]. Recently, many new FDOs have been developed with the exponential and Mittag-Leffler kernels to analyze the systems and models with better memory characteristics. In this sequence, the latest work includes the investigations of the exothermic model and vibration equation of fractional order with the inclusion of the power law and the Mittag-Leffler law by Kumar et al. [4, 5]. The researchers used the Laplace transform and the Elzaki transform to solve fractional differential equations, in addition to a system of partial differential equations [6, 7]. Caputo-Fabrizio and other fractional operators have been utilized to examine the solution behavior of fractional-order models. In the year 2018, Evirgen and Yavuz [8] investigated an alternative scheme for a nonlinear optimization problem containing the CF operator. With the utilization of the semianalytical schemes HPSTM and HASTM, the solutions obtained via HPSTM are in good correspondence with the semianalytic solutions obtained by using HASTM [9]. This indicates that one can try to solve partial differential equations using the same techniques for conformable fractional derivatives (CFD) suggested by Khalil [10]. Analytical solutions have been extracted from this conformable Sumudu transform, and conformable fractional derivatives were solved to construct the new exact traveling wave solutions of the three special form of time fractional WKB equations [1113], such as the time fractional approximate long-wave equations, the time fractional variant Bossiness equations, and the time fractional Wuzhang system of equations using the generalized expansion [14] method with a conformable derivative sense. They have presented a new cubic B-spline (CBS) approximation technique for the numerical treatment of coupled viscous Burgers’ equations arising in the study of fluid dynamics, continuous stochastic processes, acoustic transmissions, and aerofoil flow theory [15]. A finite difference scheme which depends on a new approximation based on an extended cubic B-spline for the second-order derivative is used to calculate the numerical outcomes of time fractional Burgers Equation (22). We have discussed the new definition of double Sumudu transformation and new conformable fractional derivative for converting the nonlinear fractional differential equations into the ODEs [16]. The conformable fractional double Sumudu transform method was applied to solve the time-space of conformable fractional telegraph differential equations. Thus, the aim of this study is to suggest an analytical solution for the one singular conformable fractional telegraph equation by using the conformable double Sumudu decomposition method.

The methodology of this paper is as follows. In Section 2, we present a double definition of Sumudu transformation, its properties, a description of conformable fractional, and fractional space-time telegraph equations. In Section 3, we obtained the exact solutions of the conformable fractional space-time telegraph equations. The conclusion from this paper is in Section 4.

2. Conformable Double Sumudu Transform and Some Properties

Now, we take into account a few definitions and properties of the CDST (conformable double Sumudu transform) which may allow for the finding of even more transformed pairs rather than having to consider the following.

Definition 4 (single conformable Sumudu transform of a function with two variables). CST (conformable Sumudu transform) with respect to of can be represented as where the integral is in the conformable sense with respect to .

The expression reveals the conformable integral of (5); in the given expression, the subscript on indicates for which variable the CST can be applied.

Homogenously, the CST of the same function with respect to variable is defined as due to these definitions, the successive transformation is represented by presented in (4). If it is assumed that the function gives adequate contraints (Love 1970), the order of transformation can be altered, as and symbolically, it can be represented as

Theorem 5. Let us assume that the two functions have CDST, then (1),where and are constants (2), where (3)(4)

Then, Similarly, the CDLT (Conformable Double Laplace Transform) of mixed partial derivative where and represent times conformable fractional derivatives of function having order and , respectively.

Applying conformable double Sumudu transform for () produces Again, employing conformable single Sumudu transform to constraints stated in Equation (34) yields after some mathematical computation in Equation (34), one can obtain So, we are going to get the solution of Equation (34) (see Figure 3):

4. Conclusion

The primary goal is the successful utilization of double Sumudu transforms to the conformable fractional-order and interesting and linear space-time conformable fractional telegraph equations. We have discussed the definition of double Sumudu transformation and new conformable fractional derivative for converting the linear fractional differential equations into the ODEs over time; we presented the general analytical solution of a linear space-time conformable fractional telegraph equations conformable fractional double Sumudu transform. Also, our suggested method is applied successfully for obtaining the general solutions of several linear and nonhomogeneous conformable fractional telegraph equations. Finally, the effects show that our resolved method is efficient and can be applied for finding the general solutions of all cases related to the conformable fractional differential equations.
