Description
Acquire the basics of measurement theory and integration, then use these foundations to introduce the spaces and tools of functional analysis.
Objectives
This UE will cover the following points:
- General measurement theory: measurable spaces, measurable applications and measured spaces.
- General theory of integration: integrals of stepped functions, positive measurable functions and real or complex functions. Monotone and dominated convergence theorems. Continuity and derivability of integrals dependent on a parameter.
- Examples of measures: image measures and the transfer theorem, counting measures on N, Lebesgue measures on Rn, product measures and Fubini's theorem.
- Lp spaces: Hölder and Minkowski inequalities, definition of Lp spaces. Convolution product and density theorems for Lp spaces on Rn.
- Fourier transform on R: definition and properties, inversion formula, example of use.
Necessary prerequisites
Analysis courses in L1 and L2, in particular :
- HAX403X Analysis 4, Function sequences, integer series, Fourier
- HAX404X Topology of Rn and functions of several variables
Recommended prerequisites: L2 maths
