Discrete nonlinear systems have become increasingly important in the past decades. To understand them, new analytical and numerical methodologies have been proposed. More accurate predictions of the solutions of systems related to physical problems are investigated in that way. It is worth noting that qualitative and quantitative features of discrete nonlinear modeling problems and simulation techniques have attracted a significant amount of attention from researchers in different branches of applied sciences. This is due to the fact that features of the solutions are crucial to our understanding of many important phenomena in nature and society. In fact, the science and engineering communities have been benefited tremendously from recent progress in the area. Interactions between the praxis and new mathematical methodologies have also reached a new high level.

Based on the above, this special issue aims at keeping track of the most relevant developments in the analysis and simulations of discrete nonlinear systems that appear in nature and society. More precisely, we pay special attention to analytical features of the solutions of the systems as well as the analysis of interactive computational strategies. Both deterministic and stochastic paradigms arising from nature and society are of interest, and pertinent applications to the resolution of realistic problems are studied. Continuous methods are within our interest as far as they provide helpful or insightful tools for the analysis. Challenging issues pertaining to the analysis of (integer- and fractional-order) partial differential equations and underlying approximation techniques are also of high relevance.

There are 49 research papers being received and undergone thorough peer-reviewing processes. There are 15 articles accepted and published in this special issue.
