# Complex Analysis II (Winter 2015/2016) Lectures Tutorials Alexander Bobenko Mon 12-14 MA 850 Tue 12-14 MA 850 Jan Techter Wed 10-12 MA 749 Thu 14-16 MA 742

### Contents

Elliptic functions, Conformal mapping, Analytic theory of differential equations

This is a course of the Berlin Mathematical School held in english or deutsch (depending on the audience).

### News

[09.02.2016]
There will be no tutorial on February 10.
The last tutorial will be on February 11.
[01.02.2016]
Exams can be taken on February 18.
Another date will be in April.
[27.01.2016]
The last exercise sheet is online (number 12).
The total number of regular points is 235.
[06.01.2016]
No tutorials on January 13 and 14.
Exercise Sheet 10 is therefore due January 21.
You can obtain 30 points on this sheet, 10 of which are bonus.
[04.01.2016]
New office of Jan Techter is MA883.
[05.12.2015]
Correction Sheet 7, Exercise 3: Some squares are missing:
The differential equations in (i) and (ii) are supposed to read $\dot{v}^2 = \dots$ and $\dot{u}^2 = \dots$ as you have already seen in the tutorial.
[02.12.2015]
Correction Sheet 6, Exercise 1:
The function $\mu:U_2 \rightarrow U_1$ is not necessarily biholomorphic, but in general only holomorphic.
[26.11.2015]
The differential you are supposed to consider in Sheet 6, Exercise 2 (i) is $\frac{d\lambda}{\mu}$.
[24.11.2015]
Correction Sheet 4, Exercise 3 (v):
It has to be $\Gamma_0 = \Gamma \cup \Gamma\cdot T_1$.
You got the points for detecting the error in this case.
[18.11.2015]
Correction in equation (3) of Exercise Sheet 5.
[17.11.2015]
No lecture on Monday, November 23.
[29.10.2015]
Note on Exercise Sheet 02 Exercise 4: Of course $f$ is supposed to be holomorphic away from singularities.
[29.10.2015]
You may hand in Exercise 4 of Exercise Sheet 02 one week later, together with Exercise Sheet 03.
[26.10.2015]
Slight correction on Exercise Sheet 01, Exercise 3 (ii) and (iii), making them a bit more precise:
It is now stated that there are no more poles than the previously given ones.
[26.10.2015]
The Thusday tutorial is now at 14-16 in room MA742.
[10.10.2015]
First lecture on Monday, October 12.
No lecture on Tuesday, October 13.
First tutorials in the second week.

### Homework policy

• The exercises are to be solved in groups of two people.
• The exercise sheets will usually be online on Tuesdays.
They are to be handed in at the beginning of the tutorial, one week later.
• To get a certificate for the tutorial, you need to satisfactorily complete 50% of the homework assignments.
