Description
In the first part: deepen the basic notions of differential calculus seen in L2.
In the second part: introduce the qualitative study of differential equations.
Objectives
This UE will cover the following points:
Differential calculation
- definition of differential, finite increase inequality, Ck class functions, Taylor formula.
- Notion of diffeomorphism, local inversion theorem, global inversion, implicit function theorem.
Differential equations
- Maximum solution, global, Cauchy Lipschitz theorem, finite-time explosion, global Cauchy Lipschitz theorem, exit theorem for any compact.
- Linear differential equations: linear Cauchy Lipschitz theorem, constant operator linear systems, general linear systems
- Autonomous equations and vector fields: flow and integral curve of a vector field, stable and unstable equilibrium. Autonomous differential systems of size 2.
