Objectives
We aim to provide an introduction to important methods and examples of determinstic and stochastic mathematical modeling based on differential and difference equations. Many examples will be discussed, taken from diverse domains of applications, from Natural Science (Physics, Chemistry, Biology) to Engineering, and Social Science. A particular focus will be generic behavior induced by the nonlinear nature of the models studied, such as deterministic chaos, pattern formation. and other. As more specific objectives, we can highlight: - To be able to formulate a practical model in terms of conservation and constitutive laws, in a consistent way from the point of view of physical dimensions, identifying the main dimensional constants and dimensionless constant ratios characterizing it. - To become familiar with paradigmatic modeling approaches in Science, Engineering, and Socioeconomic systems through ordinary differential equations, discrete maps, and partial differential equations. - To become familiar with discrete or continuous-time stochastic models provided by important Markov processes. - To have a working knowledge of the qualitative theory of dynamical systems. - To get acquainted with bifurcation phenomena in low-dimensional dynamical systems and partial differential equations. - To be able to identify and characterize chaotic behavior in discrete and continuous low-dimensional deterministic systems. - To be acquainted with further nonlinear phenomena in spatially-extended systems, such as reaction-diffusion processes, wave behavior, or pattern formation. Basic competences: CB6, CB7, CB8, CB9, CB10 General competences: CG1, CG2, CG3, CG4, CG5, CG6, CG7 Specific competences: CE1, CE2, CE3, CE4, CE5, CE6, CE7, CE8, CE9, C11

Learning activities and methodology
- Theory sessions: These enable acquiring the specific cognitive competences of the course, via discussion of the theoretical content of the course. To facilitate following these lectures, students will receive related materials (notes, presentations, links), as well as access to the bibliography which allows to complement and/or delve further into various aspects, as needed. - Practical sessions: These are devoted to solution of examples and exercises, practice in the computer room, or student presentations. These lectures allow to develop specific competences and will alternate with the theoretical ones. Tutorial learning activities are also foreseen, both of theoretical and practical content, which albeit also suited for autonomous work, require some form of supervision by the Instructor. These activities may include e.g. scheduled or follow-up tutorial sessions, of practice supervision. Remaining activities are unsupervised autonomous of group work, focused on additional reading, exercises, and practice, with open access to the computer room if required.
