Special Issue Information

Dear Colleagues,

Nonlinear partial differential equations (NPDEs) are an important branch of modern mathematics and are currently the main focus of differential equation research, including integer order partial differential equations and fractal and fractional NPDEs. Fractal and fractional NPDEs are derivatives and extensions of traditional nonlinear integer order differential equations, and their properties are more complex than traditional nonlinear integer order equations. In recent years, the exact solutions of the NPDEs have been a focus of research. This special issue, therefore, calls for the submission of high-quality research papers with an emphasis on the latest developments of the computational methods for fractal and fractional NPDEs. Topics include, but are not limited to, the following:

  1. Methods for the fractal and fractional nonlinear partial differential equations;
  2. Fractal and fractional partial differential equations in physics;
  3. Advanced theory of fractal and fractional calculus;
  4. Fractal variational principle;
  5. Fractal and fractional soliton solutions;
  6. Travelling wave solutions;
  7. Chaotic behaviors of the fractal and fractional partial differential equations;
  8. Two-scale transform.

In this study, we investigate the fractional Tzitzéica equation, a nonlinear evolution equation known for modeling complex phenomena in various scientific domains such as solid-state physics, crystal dislocation, electromagnetic waves, chemical kinetics, quantum field theory, and nonlinear optics. Using the (G′/G, 1/G)-expansion approach, we derive different categories of exact solutions, like hyperbolic, trigonometric, and rational functions. The beta fractional derivative is used here to generalize the classical idea of the derivative, which preserves important principles. The derived solutions with broader nonlinear wave structures are periodic waves, breathers, peakons, W-shaped solitons, and singular solitons, which enhance our understanding of nonlinear wave dynamics. In relation to these results, the findings are described by showing the solitons’ physical behaviors, their stabilities, and dispersions under fractional parameters in the form of contour plots and 2D and 3D graphs. Comparisons with earlier studies underscore the originality and consistency of the (G′/G, 1/G)-expansion approach in addressing fractional-order evolution equations. It contributes new solutions to analytical problems of fractional nonlinear integrable systems and helps understand the systems’ dynamic behavior in a wider scope of applications. Full article

A clear method is provided to explain a new approach for solving systems of fractional Navier–Stokes equations (SFNSEs) using initial conditions (ICs) that rely on the Elzaki transform (ET). A few steps show the technique’s validity and utility for handling SFNSE solutions. For fractional derivatives, the Caputo sense is used. This method does not need discretization or limiting assumptions and may be used to solve both linear and nonlinear SFNSEs. By eliminating round-off mistakes, the technique reduces the need for numerical calculations. Using examples, the new technique’s accuracy and efficacy are illustrated. Full article
