TEACHING MATERIALS AULAWEB

OVERVIEW

The theory of Markov chains is presented, both at discrete and continuous time, with particular attention to Poisson processes and queuing theory. The goal is to provide the student with the ability to model real problems of stochastic evolution in terms of Markov chains (when possible). 

Teaching contributes to the achievement of Goals 4 and 5 of Sustainable Development of the UN 2030 Agenda.

 

AIMS AND CONTENT

LEARNING OUTCOMES

The purpose of the teaching is to introduce the theory of Markov Chains and to develop the skills necessary to model by means of such processes dynamic systems that evolve randomly, and solve problems related to them.

AIMS AND LEARNING OUTCOMES

The goal is to have the student learn the language of Markov chains, so that he will be able to build an accurate model starting from real problems of stochastic evolutions taking values in a finite or countable set (the set of states). 

At the end of the course the student will have to:
- know the general theory of Markov chains, both at discrete and continuous time,          

- classify the states and determine the invariant laws with respect to the evolutions of the system,                                                          

- suitably model real situations of the queueing theory in the language of Markov chains, and be able to study the efficacy of the model. 

 

 

PREREQUISITES

Probability.

You can find more details on Aulaweb.

TEACHING METHODS

Teaching is done the traditional way, with lectures held at the blackboard. Expect 2 theory classes per week (4 hours) and 1 of exercises (2 hours).
At the end of the course there will be a guided full-text exercise so as to give students the opportunity to understand their degree of readiness and to clarify together possible doubts. 

Attendance is not mandatory but strongly recommended.

EXAMS

EXAM DESCRIPTION

Written test + oral test. 
To participate in the written test you must register on the UNIGE site.
The written exam is only passed by scoring greater than or equal to 18 marks out of 30. The oral examination can be taken immediately after the written test or even in subsequent exam sessions during the academic year in progress. 

The written test consists of 2 exercises, one on the discrete part and the other one on the continuous part.
The duration of the test is 3 hours and access to the course notes (including exercises done in the classroom) and handouts is allowed. 

The oral test will consist of exposition of theoretical arguments, proofs and exercises. Students in the master's degree in mathematics will also be asked for a proof (of the teacher's choice) from among those not given in class.

Students with DSA certification ("specific learning disabilities"), disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination methods that, in compliance with the teaching objectives, take account of individual learning arrangements and provide appropriate compensatory tools. in order to request these supports, the instructions detailed on Aulaweb https://2023.aulaweb.unige.it/course/view.php?id=12490#section-3 must be followed; in particular, support must be requested significantly in advance (at least 10 days) of the exam date by writing to the teacher with the School Contact Teacher and the appropriate Office in copy (see instructions). "

 

Mathematical Statistics: Written and oral exam. 

 

For Smid students, the final grade will be given by the weighted average (over the CFUs) of the grades for the two parts of the teaching.

ASSESSMENT METHODS

The oral examination is aimed at assessing the general understanding of the course topics and it is required that the student knows how to properly expose the concepts seen in the course, to show the main results and to solve the exercises.

The written grade is the starting point for the final score, and it is modified depending on the oral performance, either positively or negatively.

FURTHER INFORMATION

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Sergio Di Domizio (sergio.didomizio@unige.it), the Department’s disability liaison.
