# Stochastic Processes WS 17/18

## News

[16.02.18] There is news about the retake exam. Check the exam section![02.02.18] We changed exercise H1 a) and H2 of sheet 14 slightly.

[08.01.18] There is news about the exam. Check the exam section!

[21.12.17] Here is a note on H2 of sheet 5. In the exercise class it was assumed that the process on sheet 2 converged to Brownian bridge in distribution, however on we only proved this for the finite dimensional distributions. This note now gives the proof assuming only the convergence of the finite diminensional distributions.

[01.12.17] In the week of 11-17 December the exercise class and the Thursday lecture will be swapped.

[01.12.17] We changed exercise H4 of sheet 7 to be somewhat easier and added a hint.

[09.11.17] There will be no lecture on Thursday, the 16th of November.

[09.11.17] Exercise H2 of sheet 4 has been formulated more precisely.

[09.10.17] There will be a lecture instead of an exercise class on Tuesday in the first week. (17th of October)

The exercise sheets are posted every Tuesday, the homework will be due on the next Tuesday at 14:00. Please put your homework in homework box 56 on the first floor, or hand it in during the exercise class.

You can get a bonus for your grade, the height of which depends on the amount of points obtained from the homework exercises, with thresholds at 50% and 75% of the total amount of points. To keep track of your points it is

**necessary that you are registered**for the course. The homework is to be handed in individually, but working together is strongly encouraged.

The homework will be graded by Florian Ingerl, he can be reached at imelflorianingerl [AT] gmail [DOT] com. It will be handed back in the exercise class in the next week.
