Course objectives
Topics taught in this class are essential tools required to a statistician and a probabilist. They are fundamental for any modern mathematician. Students re-think to subjects of their undergraduate studies with a different level of abstraction.This new approach allows them to control some advanced methods of probability theory, useful for applications as wel as for research.

Results of learning outcomes
Students attain a detailed knowledge of the foundations of the theory of probability and related topics in measure theory. They attain good ability in probabilistic problem solving becoming able to deal both with theoretical and applied problems related with conditional expectation, convergence features, characteristic functions and martingales.
They become able to prove new results related with the studied theory, furthermore they become used to learn using different textbooks.- Oggetto:
Course delivery
There will be 72 hours of lessons, including 16 hours of in class exercises. Personal training on assigned exercises is important for the success in this class.

Learning assessment methods
Final exam includes written and an oral tests. The two tests are scheduled on different dates. The written test holds until the next oral exam. Written test request the solution of two exercises and it is mandatory to pass this test to be admitted to the oral test. The oral examination includes a discussion on the written test as well as the answer to two question, taken at random by the student. Students can use textbook during the written test.
During the written test you can use books (any number you wish) but personal notes are not allowed. Peronal notes inside the books should be eliminated to use the book during the exam.

Note
Final written exam a.a. 2016-17, sessions of January and February 2017:
- all the handed homeworks are well done. Students can complete the written exam by solving the exercise on Martingale.
- the evaluation of the written exam will account for:
the exercise on Martingale
the handed homeworks.
- the final evaluation will account both for the written and the oral exams. The oral will be on the whole program.
Students who have not handed homeworks should advise Prof Sacerdote in advance that they need to complete the written part consisting of exercises on the whole program. From the sessions of June all the students will complete the exam with a written and an oral exam on the whole program.
Attention: students must register on the exams web-page to be admitted to the written/oral exams (in time). Not registered students will not be admitted being impossible to register their final mark.
