Abstract:In this paper, the problem of constructing the Lie point symmetries group of the nonlinear partial differential equation appeared in mathematical physics known as the generalized KdV-Like equation is discussed. By using the Lie symmetry method for the generalized KdV-Like equation, the point symmetry operators are constructed and are used to reduce the equation to another fractional ordinary differential equation based on Erdélyi-Kober differential operator. The symmetries of this equation are also used to con… Show more

“…Later, Gazizov proposed the generalization of the Lie symmetry method for fractional diferential equations (FDEs) by developing prolongation formulas for fractional derivatives. Since then, numerous studies have been conducted to investigate FDEs using the Lie symmetry method, see [11][12][13].…”
In this study, the classical Lie symmetry method is successfully applied to investigate the symmetries of the time-fractional generalized foam drainage equation with the Riemann–Liouville derivative. With the help of the obtained Lie point symmetries, the equation is reduced to nonlinear fractional ordinary differential equations (NLFODEs) which contain the Erdélyi–Kober fractional differential operator. The equation is also studied by applying the power series method, which enables us to obtain extra solutions. The obtained power series solution is further examined for convergence. Conservation laws for this equation are obtained with the aid of the new conservation theorem and the fractional generalization of the Noether operators.

“…Rashidi and Hejazi [25] in their work used LSA to attain the solutions of a fractional integro-differential system called the Vlasov-Maxwell system. Bahi and Hilal [26] used LSA to find the CLs and exact solutions of the generalized time-fractional Korteweg-de Vries-Burgers-like equation. Liu et al used LSA on generalized time-fractional diffusion equations and also derived the CLs and exact solutions of the model [27][28][29][30][31][32].…”
In this article, we explore the famous Selkov-Schnakenberg (SS) system of coupled nonlinear partial differential equations (PDEs) for Lie symmetry analysis (LSA), Self Adjointness (SA) and Conservation laws (CLs). Moreover miscellaneous soliton solutions like dark, bright, periodic, rational, Jacobian elliptic function (JEF), Weierstrass elliptic and hyperbolic solutions of SS system will be achieved by a well-known technique called Sub-ODE. All these results are displayed graphically by 3D, 2D and contour plots.
“…In [37], an inquiry was undertaken to increase the reliability and precision of a genetic programming-based method to deduce model equations from a proven analytical solution, especially by using the solitary wave solution; the program, instead of giving (2), surprisingly gave the fractional KdV-like equation. By using the KdV-like equations, we can find other properties of the classical equation (see [25,32,[38][39][40][41][42]). The paper is arranged as follows.…”
In this paper, Lie symmetries of time-fractional KdV-Like equation with Riemann-Liouville derivative are performed. With the aid of infinitesimal symmetries, the vector fields and symmetry reductions of the equation are constructed, respectively; as a result, the invariant solutions are acquired in one case; we show that the KdV-like equation can be reduced to a fractional ordinary differential equation (FODE) which is connected with the Erdélyi-Kober functional derivative; for this kind of reduced form, we use the power series method for extracting the explicit solutions in the form of power series solution. Finally, Ibragimov’s theorem has been employed to construct the conservation laws.
