• Learning Outcomes
##### Course Learning Outcomes
In 2020, the topic of this course is Algebraic topology

Description: The aim of Algebraic Topology is to use algebraic structures and techniques to classify topological spaces up to homeomorphism. Algebraic objects are associated to topological spaces in such a way that "natural" operations on the latter correspond to "natural" operations on the former - continuous maps correspond to group homomorphisms, homeomorphisms to isomorphisms, etc. In this way, it is often possible to distinguish between different topological spaces by demonstrating that certain associated algebraic objects are not isomorphic. It is rarely the case that the converse can be shown; i.e., that two topological spaces with the same associated algebraic objects are actually homeomorphic, but when this can be done, it is often regarded as a major triumph of the theory.

Within the realms of algebraic topology, there are several basic concepts that underly the theory and serve as the building blocks and models for subsequent generalisation, the algebraic topology of today being a very broad and highly generalised area that has pervaded much of contemporary mathematics. Such concepts include homotopy, cohomology, and homological algebra and the course will be aimed at providing students with an introduction to these key ideas.

Key Phrases: Fundamental group, covering spaces, cohomology, homological algebra

Assumed
Knowledge: It will be assumed that you have some familiarity with basic point-set topology (or at least metric spaces) and familiarity with  basic notions of abstract algebra (groups, rings, fields etc.) However I will give a review of point-set topology in the first few lectures.

Learning Outcomes:

On successful completion of this course, students will be able to

1) understand the basic notions of homotopy theory such as homotopy of maps, homotopy equivalences, contractible spaces, fibrations
2) define the fundamental group of a (path connected) topological space and be able to compute fundamental groups of some simple examples using for example the Seifert-van Kampen Theorem,
3) define the singular cohomology groups of a topological space and their relative versions,
4) understand and work with basic concepts in homological algebra, including chain complexes and long exact sequences,
5) compute the cohomology of some topological spaces,
6) apply the topological invariants constructed in this course to the solution of various problems in topology, for instance, to prove that
two spaces are not homeomorphic.

This course will provide students with an opportunity to develop the Graduate Attribute(s) specified below:

• Learning & Teaching Activities
##### Learning & Teaching Modes
The 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.

• Assessment

The University's policy on Assessment for Coursework Programs is based on the following four principles:

1. Assessment must encourage and reinforce learning.
2. Assessment must enable robust and fair judgements about student performance.
3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
4. Assessment must maintain academic standards.

##### Assessment Summary
 Component Weighting Learning Outcomes Assignments 20% all Test 20% all Exam 60% all
##### Assessment Related Requirements
An aggregate score of 50% is required to pass the course.
##### Assessment Detail
There will be a total of 5 homework assignments, distributed during each even week of the semester and due at the end of the following week. Each will cover material from the lectures. There will be a midterm test in the week preceeding the midterm break covering approximately the first one third of the course. There will be a final exam focussing on, but not limited to, the last two-thirds of the course.
##### Submission
Homework 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:

M11 (Honours Mark Scheme)
Fail A mark between 1-49 F
Third Class A mark between 50-59 3
Second Class Div B A mark between 60-69 2B
Second Class Div A A mark between 70-79 2A
First Class A mark between 80-100 1
Result Pending An interim result RP
Continuing Continuing CN

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.

• Student Feedback

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.

• Student Support
• Policies & Guidelines
• Fraud Awareness

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 studentâ€™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.
