Textbook: Introduction to Topology, Second Edition, by Theodore
Gamelin and Robert Greene, Dover 1999
Course description: Topology is the study of the shape of objects.
It considers properties that do not change under stretching and
bending, and is fundamental to many areas of mathematics: geometry,
analysis, and even an area as apparently non-geometric as number
theory. Topology also has applications in computer science (distributed
computing) and biology (tangled DNA). Some objectives of this course
will be to understand metric spaces and topological spaces,
particularly properties these spaces may have such as compactness,
connectedness and separability. We will also look at techniques
for obtaining new spaces from old ones, such as product spaces and
quotient spaces. Carefully selected examples will develop our intuition
for the subject and motivate the results we find. At the end of
the course we will learn how to distinguish topological spaces from one
another using topological invariants related to combinatorics and
algebra, such as the Euler characteristic, the fundamental group, and

Homework: There will be several homework assignments (graded). The
homework score makes up for 40% of your total grade in this class.
Please make sure to hand in the homework before
its due date, as I do not accept late homework (for any reason). You
discuss homework with other students, or look for other resources, but
you are expected to write the solutions on your own.
Midterm: There will be an in class midterm, its projected date is Wednesday,
March 7. This will be 30% of the total grade.
The final exam is also in class, on the date scheduled by the registrar. The final exam is 30% of the total grade.
