This work presents a fast and efficient approach for solving the Fokker–Planck equation via the Laguerre wavelet collocation method. Properties of the Laguerre wavelet are presented, along with the Laguerre basis to reduce the problems into systems of either linear or nonlinear algebraic equations. This system is then solved to find the unknown coefficients. A convergent analysis for the proposed scheme is explained through theorems. Several numerical examples are presented to demonstrate the applicability and accuracy of the method to a wide variety of similar problems. The results are compared to other methods through graphs and tables. [ABSTRACT FROM AUTHOR]

Fractional Brusselator reaction‐diffusion system (BRDS) is used for modeling of specific chemical reaction‐diffusion processes. It may be noted that numerous models in nonlinear science are defined by fractional differential equations (FDEs) in which an unknown function appears under the operation of a fractional‐order derivative. Even though many researchers have studied the applicability and practicality of this model, the analytical approach of this model is rarely found in the literature. In this investigation, a novel semi‐analytical technique called fractional reduced differential transform method (FRDTM) has been applied to solve the present model, which is characterized by the time‐fractional derivative (FD). Obtained outcomes are compared with the solution of other existing methods for a particular case. Also, the convergence analysis of this model has been studied here. [ABSTRACT FROM AUTHOR]

The nonlinear dynamics of deoxyribonucleic acid (DNA) is the subject of this research. For an organism to flourish and reproduce, it needs the genetic information that is contained in its DNA. In the DNA molecule, the hydrogen bonds between the base pairs of the two polynucleotide chains are represented by an elastic membrane (or a series of linear springs) that connects the model's two long elastic homogeneous strands (or rods). Using two integration norms, namely, the new auxiliary equation method (NAEM) and the extended sinh‐Gordon equation expansion method (ShGEEM), we obtain a variety of nonlinear dynamical solitary wave structures in various shapes, including hyperbolic, trigonometric, and exponential function solutions, as well as some unique solitary wave solutions, including bell‐shaped, kink, singular, combined, and multiple solitons. Using the logarithmic transformation assistant, we examine a variety of wave structures and recover singular periodic wave solutions with unknown parameters, along with the validity constraints. According to the results, the governing model contains an unusually large number of theoretically exact solitary wave solutions. The physical characterization of some of the presented results can be visualized in 3D and 2D profiles by selecting the appropriate parameter values. [ABSTRACT FROM AUTHOR]

In the paper, we search for some analytical solutions for a new (3 + 1)‐dimension Boiti–Leon–Manna–Pempinelli (BLMP) equation. Based on the Hirota bilinear method, bilinear neural network framework expands to more than one hidden layer to construct test functions. By using the symbolic computation software Maple, periodic‐type I, II, and III solutions of the new (3 + 1)‐dimension BLMP equation are obtained. Besides, the evolution and dynamical characteristics of these solutions derived via the appropriate real values are also exhibited. [ABSTRACT FROM AUTHOR]
