Description
This course covers the notions of function sequences and series, and the various convergences. Integer and Fourier series will also be developed.
Objectives
Sequence of functions Simple convergence and uniform convergence of a sequence of functions
- Definitions and link between simple and uniform convergence of a sequence of functions
- Uniform Cauchy criterion
- Dini theorems
- Stone Weierstrass theorem using Bernstein polynomials
- Stability of continuity (resp. derivability, integration) by uniform convergence
Function series
- Simple and uniform convergence
- Normal convergence
- Continuity, derivability, integrability of a series of functions
Integral series.
Definitions, radius of convergence, Hadamard's formula, d'Alembert's rule.
Properties of the sum of the whole series: continuity, derivability, integrability.
Functions that can be developed into an integer series.
Applications to solving differential equations: solving matrices by integer and exponential series.
Fourier series.
- Why Fourier series (issues and definitions)?
- Convergence (root mean square, simple, normal) of Fourier series
- Applications to series calculations and differential equations
