Set 6.

The first part of Homework 6. consists of some reading in group theory:



Here is also a summary for what we covered so far:
homotopy of paths (uses different notation, unfortunately)
The fundamental group is an algebraic group indeed
fundamental group, dependence on the basepoint
Induced homomorphism

MIDTERM INFO

The midterm will be on March 29th, Thursday, during class time.
Here is a summary+practice problems. We will also go through the last practice set.

For the point-set topology part we were loosely following Chapters 1 and 2 of Thomas Ward's Notes.

Here is a summary on the Euler characteristic for surfaces

For our next topic - the classification of compact, connected surfaces - we will look at the proof from William Massey's "Algebraic Topology: An Introduction".

Administrative issues:

The class will meet We 8:30--10.00 and Thu 10:15-11:45 in room 105 (at least the first three weeks).

Homework will be collected on Thursdays. Collaboration is allowed - moreover, encouraged, for studying and problem solving -, but everyone has to write up the solutions to the homework problems themselves.
There will be one Midterm (date to be determined later) and a Final.
The grade will depend on the homework (scaled to 100pts total), the Midterm (100pts) and Final (100pts). The Final will be comprehensive.

FYI

  • In topology a cube is a sphere as one can be continuously deformed into another.
