Content (Syllabus outline):

  • Measures: σ-algebras, positive measures,  outer measures, Caratheodory’s theorem, extension of measures from algebras to  σ-algebras, Borel measures on R, Lebesgue measure on R.
  • Measurable functions: approximation by step functions, modes of convergence of sequences of functions, Egoroff’s theorem.
  • Integration: integration of nonnegative functions, Lebesgue monotone convergence theorem, Fatou’s lemma,  integration of complex functions, Lebesgue dominated convergence theorem, comparison with Riemann’s integral.
  • Product measures:  construction of product measures, monotone classes,  Tonelli’s and Fubini’s theorem, the Lebesgue integral on Rn .
  • Complex measures: signed measures, the Hahn and the Jordan decomposition, complex measures, variation of a measure,
  • absolute continuity and mutual singularity, the Lebesgue-Radon-Nikodym theorem.
  • Lp-spaces: inequalities of Jensen, Hölder and Minkovskibounded linear functionals, dual spaces.
  • Integration on locally compact spaces: positive linear functionals on Cc(X), Radon measures,  Riesz representation theorem, Lusin’s theorem, density of Cc(X) in Lp-spaces.
  • Differentiation of measures on Rn :    differentiation of measures, absolutely continuous and functions of bounded variation

Objectives and competences:
Students acquire basic knowledge of measure theory needed to understand probability  theory, statistics and functional analysis.

Intended learning outcomes:

  • Knowledge and understanding: understanding basic concepts of measure and integration theory.
  • Application: measure theory is a part of the basic curriculum since it is crucial for understanding the theoretical basis of probablity and statistics.
  • Reflection: understanding of the theory on the basis of examples of application.
  • Transferable skills: Ability to use abstract methods to solve problems. Ability to use a wide range of references and critical thinking.
