Advances in Mathematical Physics Special Issue on Recent Trends in Symmetry Groups and Conservation Laws for Differential Equations Call for Papers Nowadays, several branches of the theoretical and applied sciences such as mathematics, physics, biology, economy, and finance rely on processes which are usually modeled by nonlinear differential equations. Often, it is difficult to obtain reductions and exact solutions for these models. Our aim is to highlight applications of symmetry methods to nonlinear models in physics, engineering, and the applied sciences as well as to present recent theoretical developments in symmetry groups. We invite researchers to submit their original research and review articles. This special issue is devoted to Recent Trends in Symmetry Groups and Conservation Laws for Differential Equations. Potential topics include, but are not limited to: • Novel applications in the sciences, including engineer- ing, physical, biological, and finance • Recent theoretical advances: new theoretical results on exact and approximate algebraic approaches to differential equations, including symmetries, solutions, conservation laws, invariants, linearization, and classification schemes • Lucid reviews and review articles dealing with modern and classical topics Lead Guest Editor Maria Gandarias, Department of Mathematics, University of Cadiz, Avenida Saharaui, 11500 Puerto Real, Cadiz, Spain; marialuz.gandarias@uca.es Guest Editors Mariano Torrisi, Department of Mathematics and Computer Science, University of Catania, viale A.
