Stochastic Processes (WS 2024)

Teacher: Prof. Dr. Peter Pfaffelhuber

Assistant and Tutor: Samuel Adeosun

Lecture: Mo 10-12, HS II, Albertstr. 23b

Exercises: tba

Examinations: Please check here what you need to do in order to obtain the ECTS points. In most cases, this is 50% of all credits of the exercise sheets, as well as presenting a solution two times during class for the pass/fail examination (Studienleistung). For the graded examination (Prüfungsleistung), there will be oral exams in both, BSc Mathematics and MSc programs.

General: The lecture contains (english) videos, which basically explain the content of the manuscript. During the lecture on Mondays, there will be a repetition of the videos. Here, you have the possibility to ask questions and interact with other people. There will be a new exercise sheet every Tuesday, which you have to hand in by Monday in then following week. It is best to do this in the mailbox in the basement of the Ernst-Zermelo-Str. 1. Two students can work together and hand in their solutions together.

Manuscript: The current version of the manuscript is here. There is also an older (German) version of the manuscript, which can be found here. Note that the manuscript builds upon the mansucripts on measure theory and probability theory.
