Unit outline

Canvas webpage

The MATH3061 Canvas webpage contains details about consultations, assessment, textbooks, objectives, and learning outcomes for MATH3061.

Geometry
This part of the course will explore geometric transformations and properties that are invariant under these transformations.

Week 1
Linear algebra review. The Euclidean plane. Transformations. Isometries.
Week 2
Transformation groups. Reflections. Fixed points. Rotations.
Week 3
Involutions. Glide-reflections. Classification of isometries. Parity.
Week 4
Symmetry groups. Affine transformations. Derivative of an isometry.
Week 5
The projective plane. Projective lines. Collineations.
Week 6
Conics. Classification of Conics.
Topology
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. Knot determinants, n-colourings, Seifert surfaces, and knot genus.

Lecture notes will be published in the resource table below.

Supplementary notes for both parts of math3061 are available online: These notes are also available as one book from Kopystop, 36 Mountain Street, Broadway.
