MA3F1 Introduction to topology
Term I 20142015

Module Description
This module, MA3F1
(Introduction to topology) has the prerequisites MA222
(Metric spaces) and MA249
(Algebra 2).
Topology is the study of shapes: the study of spaces forgetting all
notions of geometry. We begin by saying precisely what it means for
two spaces \(X\) and \(Y\) to be "the same" in the topological
setting. This done we investigate one of the most powerful
topological invariants: the fundamental group \(\pi_1(X)\). The
justly named fundamental group is related, inside topology, to
covering spaces and related, for example in number theory, to Galois
groups.
The material covered in this module is directly relevant to MA3H5
(Manifolds), MA3H6
(Algebraic topology), and many others.

Schedule
The schedule has a planned list of
topics, organized by lecture. We will change the schedule as
necessary, as we work through the material. Links to example sheets
will be posted weekbyweek.

Reference materials
We will closely follow the first chapter of the book Algebraic
topology, by Allan
Hatcher. The book is available from the website above, and can
also be purchased from the university bookshop
or online.

Example sheets
See the schedule for the example
sheets.
In addition to the exercises prepared for this class, please note that
Hatcher's book contains many interesting exercises. He has also given
additional
exercises. Here is the webpage for this module as taught by
Professor Mond in 2012.

Exam
The exam will be 85% of your mark. The exam will be closed book.
Here are the exam
papers for this module from the last four years.

Assessed work
Assessed work will be 15% of your mark. Of this, 2% (at most) may be
earned every week (starting the second week) by turning in a
single worked exercise. Please let me (Saul) know if any of
the problems are unclear or have typos.
Homework solutions must be placed in the dropoff box (near the front
office), by 15:00 on Mondays.
No late work will be accepted. Please
write your name, the date, and the problem you are solving at the top
of the page. If you collaborate with other students, please include
their names. Solutions typeset using LaTeX are preferred. Please
limit your solution to one piece of paper  if more space is needed
then write out a complete solution and then rewrite with conciseness
in mind.

Mistakes
Please tell me in person, or via email, about any errors on this
website or made in class. I am especially keen to hear about
mathematical errors, gaffes, or typos made in lecture or in the
example sheets.
