In the last decades, more and more attention has been paid to nonlinear problems of various types such as moving boundary problems, time delay problems, and fractional differential equations owing to their important and potential applications in science and engineering. Different from numerical techniques, analytical approaches can give explicit solutions to these problems, which could reflect the internal nature of the physical problems and provide easy-to-use explicit formulae for estimation of various physical quantities. We invite researchers to submit their up-to-date research work on various aspects of complicated nonlinear equations and their applications to other applied sciences by means of various analytical approaches. Potential topics include, but are not limited to:

• New theoretical researches on analytical techniques for all kinds of complicated nonlinear problems
• New applications of analytical approaches to moving boundary problems, time delay problems, fractional problems, and so forth
• Linear or nonlinear problems with complicated initial/boundary conditions
• Applications of analytical approaches in partial differential equations
• Improvement of analytical approaches and their applications in science and engineering problems
• New applications of the iterations method in science and engineering
• Analytical methods for fractional differential equation
• Nonlinear perturbation differential equation
• Numerical analysis of nonlinear differential equations
