Nonlinear PDEs and Applications

Brief description

Most of the relevant models in Applied Mathematics in connection with other Sciences and Engineering are formulated in terms of Nonlinear Partial Differential Equations (PDEs). The interdisciplinary treatment of many complex problems require to build different models which allow to have predictions previous or simultaneous to experimental studies. The spectrum of problems formulated in terms on nonlinear PDEs is very large and cover dynamical frameworks as well as their associated stationary regimes. Moreover, besides the direct approach involving the existence, uniqueness and regularity of solutions in suitable functional spaces well adapted to the model the mathematical treatment is completed with the consideration of inverse formulations and the control of the data in order to get desired properties to be satisfied by the solutions. In fact, the numerical approach also requires a suitable functional framework leading to convergent algorithms. Among the list of problems considered in this Program we mention the occurrence of strange terms in homogenization to critical scales, localizing formulations in linear and nonlinear Schrodinger equations, Reaction- Diffusion systems arising in Climatology and Chemical Engineering, Stochastic PDEs, Lithium batteries models, systems of equations in population studies, Image Processing and so on. In addition, the extension and generation of new mathematical techniques to deal with non-local formulations will be also carried out.
