Suggested background knowledge

Mission & Content Summary

MISSION

Mathematics is the language in which most of modern sciences and economics is written. The course aims to provide basic and sophisticated mathematical tools that students need in order to tackle data science challenges and advanced economics studies. The course develops the mathematical point of view of optimization, aiming to form the modeling and thinking skills that students will need later on, during both their academic and professional careers.

CONTENT SUMMARY

  • Basics on differential equations, separation of variables, linear equations, linear systems. Quick overview of some nonlinear equations.

  • Vector spaces, Banach spaces, Hilbert spaces. Separable spaces: $ell^2$ and $L^2_T$. Operators: norms and fixed points.

  • Continuity, convexity, compactness. Fréchet-derivatives. Fixed points, contractions.

  • Classical problems in calculus of variations, critical points. Maxima and minima, necessary/sufficient conditions. Convexity.

  • Control theory, bang-bang principle. Hamiltonians, the Pontryagin maximum principle.

  • Dynamic programming. The Hamilton-Jacobi-Bellman equation.
