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 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:
