Special Issue Information

Dear Colleagues,

The study of nonlinear phenomena is concerned in the field of natural science and even social science.

Since many phenomena in nature are essentially nonlinear, nonlinear phenomena have aroused the interest and concern of engineers, physicists, mathematicians, and many others. In the mathematical and physical sciences, nonlinearity is the phenomenon that the change in output is not proportional to that in input. A large part of nonlinear phenomena can be described by nonlinear partial differential equations.

It is often possible to find several particular solutions for nonlinear problems; however, it is commonly very difficult to find general solutions from these particular solutions. Hence, it is necessary to study the numerical theory and numerical simulation of the nonlinear evaluation equation.

This Special Issue addresses the newest development for the nonlinear evolution problems involving shallow water problems, nonlinear phase field equation, nonlinear modeling turbulence, nonlinear quantum mechanics, nonlinear bioinformation, nonlinear delay differential equations, nonlinear fractional problems with their possible applications in any area of science and engineering.

In this paper, an efficient and straightforward numerical procedure is constructed to solve multi-dimensional linear and nonlinear elliptic partial differential equations (PDEs). Although the numerical procedure for the constraint-type fictitious time integration method overcomes the numerical stability problem, the parameter’s definition, numerical accuracy and computational efficiency have not been resolved, and the lack of initial guess values results in reduced computational efficiency. Therefore, the normalized two-point boundary value solution of the Lie-group shooting method is proposed and considered in the numerical procedure to avoid the problem of the initial guess value. Then, a space-time variable, including the minimal fictitious time step and convergence rate factor, is introduced to study the relationship between the initial guess value and convergence rate factor. Some benchmark numerical examples are tested. As the results show, this numerical procedure using the normalized boundary value solution can significantly converge within one step, and the numerical accuracy is better than that demonstrated in the previous literature.
