[2016, July 18]
Somebody accidentally handed in a corrected exercise sheet of something that looks like Financial Mathematics. It is signed by M.V.
[2016, July 18]
There is now a Bonus Exercise Sheet online which you may hand in together with Exercise Sheet 12 on Thursday, July 21.
[2016, July 18]
Corrected hint in Exercise Sheet 12, Exercise 2.
[2016, July 07]
Exercise Sheet 10, Exercise 2: $\varphi(0)$ does not have to be $0$.
One may drop this condition and define the winding number by $\nu(\gamma, 0) = \frac{\varphi(1) - \varphi(0)}{2\pi}$.
[2016, July 04]
There will be a total number of 12 exercise sheets for this course with a sum of 240 regular points.
[2016, May 17]
Sheet 3, Exercise 3 (ii): All $\varphi$ and $\phi$ should be the same, as they are now.
