The aim of the course is to broaden and consolidate the acquisition of the mathematical method as a fundamental investigation tool for economic, financial and business disciplines. To this end, we will first provide notions of linear algebra and tools to deal with constrained and unconstrained optimization problems. Then, the fundamental tools for the study of discrete and continuous dynamical systems will be addressed.
