In order to pass the course the student should be able to
use the concepts of measurable set and measurable function;
state and explain the construction of the Lebesgue integral and use it;
apply the theorems of monotone and dominated convergence and Fatou's lemma;
describe the construction of product measure and to apply Fubini's theorem;
state and explain properties of Lp spaces;¨
define absolute continuity and singularity of measures;
apply Lebesgue decomposition and the Radon-Nikodym theorem.
