Course Learning OutcomesIn 2021, the topic of this course is DIFFERENTIAL GEOMETRY
Differential geometry is a classical subject. It is the mathematical study of geometry using calculus and differential equations. The motivation for the subject comes from navigation and map making. In 1569, the cartographer Mercator experimentally discovered his celebrated map projection in which courses of constant bearing are represented by straight lines. This was a hundred years before Newton and Leibniz introduced the differential calculus needed to understand Mercator's projection fully. Nowadays, there are many map projections with various subtle and useful properties but none is totally accurate. The fundamental reason for this is Gauss' Theorema Egregium proved in 1821, which says that a quantity now called the Gaussian curvature is intrinsically defined by measurements of distance alone. As the Gaussian curvature of the unit sphere is everywhere 1 and that of the plane is everywhere 0, any map of the earth necessarily distorts distance. In 1854, Riemann extended Gaussian curvature to higher dimensions. The resulting Riemann curvature tensor was developed and extended over the next 50 years and the differential geometry of smooth metrics was born. This theory is central in both mathematics and physics; for example, Einstein's equations of general relativity are just restrictions on the curvature of space-time. The terminology of modern differential geometry reflects its historical roots: one speaks of a manifold defined by an atlas of smooth charts et cetera and even the word geometry comes from Greek, roughly meaning measurement of earth.
* Motivation (and for smooth manifolds#)
~ Navigation and cartography
~ Celestial mechanics
~ Mathematical physics
* Surfaces in three-space
~ Inverse and Implicit Function Theorems in three dimensions
~ Euclidean normalisation: Gaussian and mean curvature
~ Affine normalisation: the Pick invariant
~ Statement of Gauss' Theorema Egregium
* Smooth manifolds#
~ Flora and fauna: vector fields, tangent and co-tangent bundles
~ Calculus on manifolds: exterior derivative, de Rham complex
~ Vector bundles: connections and curvature
* Riemannian geometry
~ Torsion and curvature
~ Proof of Theorema Egregium
~The Levi-Civita connection and Riemannian curvature
- Spaces of constant curvature: hyperbolic space
- Kaehler geometry: complex projective space
* Non-Riemannian geometry
~ Lorentzian geometry: general relativity, Einstein's equations
~ Projective differential geometry: invariants and curvature
~ Conformal differential geometry: invariants and curvature
~ Other differential geometries
# There will be some overlap with Dr David Baraglia's Topics B course on Lie Algebras.
On successful completion of this course, students will be able to
1. Define Riemannian manifolds, and understand curvature both conceptually and computationally;
2. Define other differential geometric structures and understand key examples;
3. State and prove Gauss' Theorema Egregium;
4. Understand the construction of the Levi-Civita connection and its role in Riemannian differential geometry;
5. Construct the basic invariants of projective and conformal differential geometry.
The course requires an adequate knowledge of linear algebra and multivariable calculus. It is recommended, but not required, that students in this course also take PURE MTH 7002 - Pure Mathematics Topic B on Lie Algebras given by Dr David Baraglia, in which many further examples of smooth manifolds will occur in the context and mathematical study of symmetry.

Learning & Teaching Activities
Learning & Teaching ModesThe lecturer guides the students through the course material in 30 lectures. Students are expected to engage with the material in the lectures. Interaction with the lecturer and discussion of any difficulties that arise during the lecture is encouraged. Fortnightly homework assignments help students strengthen their understanding of the theory and their skills in applying it, and allow them to gauge their progress.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.The following table is a guide to the workload for each component of the course.
Activity Quantity Workload hours Lecture 30 90 Assignments 6 66 Total 156
Learning Activities Summary1) Introduction to smooth manifolds and associated gadgets (10 Lectures)
2) Riemannian geometry (10 lectures)
3) Projective, conformal, and other differential geometries (10 lectures)
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment task Task type Due Weighting Learning outcomes Examination Summative Examination period 70% all Homework assignment Formative and summative One week after assigned 30% all
Assessment Related RequirementsAn aggregate score of 50% is required to pass the course.
Assessment DetailThere will be a total of 6 homework assignments, given out at intervals of about two weeks.
SubmissionHomework assignments must be given to the lecturer in person or emailed as a pdf. Failure to meet the deadline without reasonable and verifiable excuse may result in a significant penalty for that assignment.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
