The object of Probability Theory is the study natural phenomena that are subject to randomness. The aim of this course is the introduce the students to the axiomatic development of probability theory of Kolmogorov in the context of measure theory and the rigorous proof of the central theorems of probability theory. After the end of the course the students will know:

Syllabus
Foundations of Probability theory: Probability Spaces, random variables and measurability, Borel σ-algebras, distribution of random variables, the π-λ theorem of Dynkin and equality of measures. Mean Value: Mean value as Lebesgue integral, \(L^p\)-spaces, image-measure, integration with respect to image measures, density functions as Radon-Nikodym derivatives, distribution functions. Markov-Chebyshev inequality, Jensen inequality. Moment generating functions, Chernoff bounds. Convergence in probability, pointwise convergence of random variables and convergence theorems. Stochastic independence 1: Stochastic independence of sets, σ-algebras and random variables. Criterions of independence. Independence and expectation, convolution and sums of independent variables. Borel-Cantelli lemmas and 0-1 laws of Kolomogorov. Laws of Large numbers: proof of the weak law of large numbers, proof of the strong law of large numbers. Weak convergence of random variables and empirical law of large numbers. Stochastic independence 2: Infinite product of probability spaces, construction of independent and identically distributed sequences of random variables with a given distribution. Proof of the interpretation of probability as relative frequency via the law of large numbers.
