MA8109 Stochastic processes and differential equations
Fall 2019
Welcome to MA8109 !
This PhD course is given every second year, and usually 4th and 5th year (Master) students take it along with PhD students.
What is this course about?
- Differential equations with noisy/uncertain coefficients (stochastic differential equations), and their solutions, continuous time stochastic processes: We give a mathematical background, the main results, and some applications (more details in 'General Information' in the left menu).
Of the multitude of applications in science, engineering and other disciplines, the most famous one is perhaps the Black-Scholes model for option pricing in finance.
Who can take this course?
- Interested students at Master or PhD level.
- The level should be suitable for good 4th year students in the industrial mathematics program.
- It can be taken as a regular course (MA8109) or a 'fordypningsemne' (TMA4505).

| 08.11. | Tentative oral exam dates | We discussed in class, Friday November 8: December 11 (Wednesday) and December 18 (Wednesday) Not good for you? Send me an email with your wishes and constraints. |
| Project | Do not forget the deadlines! See below and in the left menu for more info. |
|
| Homework | Homework set 5 is now available. You can do the first 3 problems from Friday onwards. OBS: Volunteer needed to write the solution of Problem 11 in Homework set 4. |
|
| Read yourselves: | Note on Linear SDEs and Physical Brownian Motion |
|
| 05.11. | Lectures restart | Thursday November 7 16:15-18:00 room 734 SB2. Lectures will follow according to the old schedule (Thursday 16-18, Friday 14-16) until the end the semester. |
| 18.10. | Notes on existence and uniqueness | The proofs can be found in my handwritten notes from class: Strong solution of SDEs. Uniqueness and Existence |
| 17.10. | Reference group | Meeting in the break, Friday October 18. |
| Project deadlines | October 18: email me your choice of project. November 29: email me the written report. See "The project" in the left menu for more info. |
|
| Next 2 weeks | You should work on the course project. No lectures, office hours instead in my office room 1148 SB2 (note the times): Wednesday 14:15-15:00. Thursday 16:15-17:00. Friday 14:15-15:30. |
|
| Existence and uniqueness of SDEs | We use the proofs as presented in Schilling. My handwritten notes will be posted later. (There seems to be a mistake in the proof of existence in the 6th edition of Øksendal. The proof in previous editions is correct but longer) |
|
| Read yourselves | Øksendal chp. 5.3 (discussion on weak solutions and uniqueness) | |
| Problem set 3 and 4 | Available under 'Homework' in the left menu. | |
| 10.10. | Lectures | Next week: We finish the discussion on strong solutions of SDEs. Week 43 and 44: Project work, no lectures. Office hours instead, in my office room 1148 SB2. |
| Project | The project counts for 20% of the final grade. You may study any relevant topic of you own choosing, see 'The Project' in the left menu for suggestions and more information. |
|
| 03.10. | Numerics for SDEs | There will be two weeks on numerical approximation on SDEs in the course: MA8404 Numerical solution of time dependent differential equations Week 44 and 45, but check the webpage for the latest update (click above link). Students from our course are welcome to attend these two weeks. |
| Read yourselves | About the Stratonovich integral in chapter 3.3 in Øksendal. | |
| Homework | After this weeks lectures you will be able to do problem 1-3 in Homework 3. Problem set 3 is available in the left menu. |

Cannot attend, but want to take the course? - Send me an email where you include the times you are not free (have other lectures). |
| Master student? | You can take the course either as MA8109 or TMA4505 (fordypningsemne). Grades: pass/fail in MA8109, A-F in TMA4505. 4th year MTFYMA students then take a regular course instead of TMA4505 in the 5th year. |
