Information about the exam

For general information about exams, and the exam timetable, please see the University's examinations web page.

The MATH3061 exam is scheduled for 13:50-16:00 on Saturday November 24, 2016. The exam has six questions, three questions for each of the geometry and topology components of the course. Each question may be attempted. The exam is worth 66% of your final assessment.

Please note that the questions for the geometry and topology sections of the course must be answered in separate booklets.

The exam is based on all the material covered in lectures, tutorials, assignments, and the quizzes. The best way to prepare for the exam is to read through and think about your lecture notes and then to try to solve as many questions as possible (without looking at the solutions) from the lectures, tutorials, and assignments. You might like to look at the 2013 MATH3061 exam. We strongly recommend that you attempt these questions before looking at the solutions, which will be made available from this web page before November 16. Here are the solutions to this exam:

Geometry Solutions   Topology Solutions.

We recommend that you do not look at these solutions until you have first attempted to do all of the questions in the exam.

In addition, here are the questions for the 2014 exam together with the solutions for the topology questions.

Information Sheet

The MATH3061 Information Sheet contains details of the lecturers and lecture times, consultation times, tutorials, assessment, textbooks, objectives, and learning outcomes for MATH3061.

The course will closely follow the "Geometry" lecture notes by O'Brian.

Week 1
Introduction. Linear Algebra review. The Euclidean Plane. Reading: pages 1–13. [For the tutorial problem: the image of a point (x,y) under a halfturn about point P(p,q) is (2p−x,2q−y).]
Week 2
Transformations. Isometries. Translations. Reflections. Reading: pages 13–27 (skip the section on symmetries).
Week 3
Fixed points. Rotations. Glide-reflections. Classification of isometries. Reading: pages 28–40.
Week 4
Parity. Affine transformations. Reading: pages 51–58.
Week 5
The derivative of an isometry. The projective plane. Collineations. Reading: pages 67, 97–103.
Week 6
Collineations. Conics. Reading: pages 103–107, 113–115.
Week 7
Classification of Conics. Review. Reading: pages 116–121.
Topology is the study of surfaces under continuous deformation. That is, we allow ourselves to stretch surfaces but not to tear them.

Week 7
Graphs, subdivision, sums of degrees = twice the number of edges, connectedness, circuits, trees.
Week 8
Disc, annulus, torus, Möbius band, Klein bottle, sphere, projective planes, homeomorphism, stereographic projection.
Week 9
Triangulated surfaces, Euler characteristic, invariance under subdivision, cutting, pasting, boundaries, orientation, edge equation.
Week 10
Classification of surfaces, genus, oriented closed surfaces in three dimensions, handles, crosscaps.
Week 11
Platonic surfaces. Graphs on surfaces: K5 is not planar. Map colouring: the five colour theorem, the Heawood estimate for maps on surfaces.
Week 12
Knots: Polygonals knots, knots diagrams, the unknot, trefoil knots, figure eight knots, knot colouring.
Week 13
Knot determinants, n-colourings, Seifert surfaces, and knot genus.
