Geometry I:
Analytic and Projective Geometry
(Winter 2012)


This is a course of the
Berlin Mathematical School
held in English.
News
 [2.5.2013]

The next dates for Oral Exams in Geometry I are Friday 31.05. and 05.07.2013. You can register for the exam
in the secretary's office (Mathias Kall, MA 873).
 [11.4.2013]

The next date for Oral Exams in Geometry I is Friday 03.05.2013. You can register for the exam
in the secretary's office (Mathias Kall, MA 873) starting from Monday 15.04.2013.

Please read the blog entries about the end of term gettogether and shifted office hours.
 [31.1.2013]

Next week, Emanuel's office hours will be shifted from Monday 4.2. 10:3012:00 to Wednesday 6.2. 1214.
 [13.1.2013]

In exercise 9.1 it is to show that the scalar product of p and q is less or equal to 1 (not 1).

 [7.1.2013]

In exercise 8.3. one should not consider skew hexagons as they are defined,
but instead talk about nonplanar hexagons.
Hint: From the fact that a hexagon is nonplanar, you can deduce that some of
the extended edges are skew. Which ones? For some pairs of extended edges, this
is not clear and the existence of further intersection points is related to the
question, whether the hexagon is contained in a quadric of signature
(++)...

Emanuel's office hours have been changed to Monday, 10:30  12:00
 [19.11.2012]

In exercise 3 of the 4th exercise sheet, it has to be n > 1.
(The exercise sheet has been updated accordingly)

Please participate in the
doodle poll
about changing Emanuel's office hours to Monday.
 [8.11.2012]

In exercise 3 of the 3rd exercise sheet,
one should assume that the point P is not contained in the hyperplane h.

 [8.11.2012]

Two lectures in December will be held in different rooms than usual:
Monday 10.12. in MA 649
Thursday 13.12. in MA 650
 [24.10.2012]

The first exercise sheet is online.
 [17.10.2012]

The first lecture is now online.
Contents
Euclidean and noneuclidean geometry: projective, hyperbolic,
Möbius, and maybe Lie geometry. The continuation is
Geometry II: Discrete Differential Geometry.
Exercise sheets
The exercise sheets can be found
here.
Homework policy
To get a certificate of participation, you need to satisfactorily complete
60% of the homework assignments.
The exercises are to be solved in groups of two people.
The homeworks are due weekly at the beginning of the lecture on Thursday. No homework will be accepted after the deadline has passed.
Lecture notes / Blog
The idea is to interactively create lecture notes using a blog. Each
homework group of students is responsible to write up a lecture once during the
semester and publish it as a post in our blog.
To be registered as a user for the blog, please write an email to Emanuel
(huhnen[at]math.tuberlin.de) that contains your desired username (minimum 4 characters,
only lower case letters and numbers) and the email
address you want to use for the blog. An account will be created for you and
you will receive an invitation email to join the blog.
Exam / Grading
At the end of the semester, oral exams will be offered.
