## Course objectives

The course is aimed at giving the students the skills to use diffusion processes to represent different realities of practical interest. The student should use the different techniques for carrying out the analysis of the models. The student will demonstrate both the ability of self-study of advanced topics, connected to the content of the course, and the ability to collaborate. Students should also use the software Mathematica to perform some assigned simulations.

## Results of learning outcomes

At the end of the course, students will know several important methods to study stochastic models of applied interest. They will know some of the important classes of stochastic processes and will be able to study their main functional and features.

## Course delivery

Lessons (48 hours, 6 CFU) are given in lecture rooms.

## Learning assessment methods

During the course homeworks are assigned. Solution of these exercises is part of the final exam. Teamwork is allowed for this part of the work. Exam is oral. Students that do not make homeworks will solve exercises immediately before the oral exam.

The evaluation of homeworks is valid only for the Summer exam session. From September session students are required to solve exercises immediately before the oral exam.

## Program

Brownian Motion: Markov property, existence of the Brownian motion; maximum and first passage time distribution; arcosine law; iterated logarithm law; Reflected Brownian motion; Heat equation and Brownian motion; multidimensional Brownian motion.

Stationary Processes: mean square distance; autoregressive processes; ergodic theory and stationary processes; Gaussian processes

Diffusion Processes: differential equations associated with some functionals of the process; backward and forward equations; stationary measures; boundary classification for regular diffusion processes; conditioned diffusion processes; spectral representation of  the transition density for a diffusion; diffusion processes and stochastic differential equations;  jump-diffusion processes; first passage time problems for diffusion processes.

An 8 hours module, included in the courseload, will be taught by Visiting Professor Vassili Kolokoltsov on Brownian motion.
