The 19th century was the century of classical mechanics, the present one is that of relativistic and quantum mechanics, and the forthcoming century will be that of nonlinear sciences. Nonlinear phenomena appear everywhere in our daily life and our scientific works, and today represent one of the most important fields of research in science and technology. It is still very difficult to solve nonlinear problems, however, either numerically or theoretically, and even more difficult to establish models for real-world nonlinear problems. Many assumptions have to be made artificially or unnecessarily to make practical engineering problems solvable, leading to loss of important information. So one of our chief aims is to establish more reasonable nonlinear models for practical engineering problems, social sciences, economic sciences and so on, which are of interest to a large readership. Particular interest will be placed on contributions concerned with the application of variational theory to deduce field equations and boundary/initial conditions, and inverse or hybrid problems of identification of optimal aerofoils, cascades and channels with most possible engineering applications in the 21st century.
The second aim of the journal is to provide a specific medium for dissemination of research results in various nonlinear analytical methods to find approximate solutions which reveal the main physical understanding and can guide engineers to do further scientific works according to the results. We are interested in approximate solutions with physical understanding. Special attention is put upon the contributions of new approaches to strongly nonlinear systems, and financial computations with nonlinear statistics techniques and other nonlinear techniques occurring in a wide multidiscipline. Pure mathematical manuscripts dealing with nonlinear sciences are also encouraged, for rigorous mathematics is essential to the healthy development of nonlinear science. Convergence theory for new approximate analytical methods is also welcome.
Our last important aim is numerical solution of nonlinear problems. We hope that the numerical solution will reveal new phenomena that other methods can not find. Especially welcome new and promising numerical methods (for example, meshfree methods) or improvements of existing methods, but other numerical techniques such as the finite difference, finite volume method , boundary element method, and so on are also encouraged. The journal publishes only original contributions from the entire field of nonlinear sciences and their applications. Survey articles on some important issues are invited only by the editors.
Every member of the editorial board (including the honorary editors) will administer the peer-review process of submitted papers and foster publication with minimum delay. And the honorary editors will provide guidance on journal policy. The nomination of membership and sponsorship of the journal may be made at any time, and the approval must be made by the editor exclusively on the basis of academic achievements.
