Course Learning Outcomes
In 2018, the topic of this course is Introduction to topological Ktheory.
Overview
The letter 'K' in Ktheory comes from the German word Klasse, which means "class". Everyone already knows at least one Ktheory group. Natural numbers classify vector spaces via the dimension, while an integer, being a difference of two natural numbers, measures the difference between two vector spaces. This is an example of Grothendieck's construction applied to obtain the Ktheory of a point.
In the 1960s, Atiyah and Hirzebruch introduced topological Ktheory, to classify bundles of vector spaces parametrised by an arbitrary topological space. Their theory turned out to be extremely rich, having deep connections to many areas of modern mathematics such as index theory, differential geometry, operator algebras, and representation theory. In noncommutative geometry, one does not even require a topological space to define and utilise Ktheory! Because of its multifacetedness, Ktheory has also found profound applications in string theory, fundamental particle physics, and condensed matter physics.
The aim of this course is to provide a gentle first introduction to the vast and interdisciplinary subject of Ktheory, as an invitation to further study and more abstract treatments of the subject. The target audience is finalyear undergraduates and beginning graduate students. The approach will be quite concrete, with only the simplest version of Ktheory to be discussed.
Prerequisites
 Linear algebra (inner product spaces, adjoints, traces, determinants), abstract algebra (groups and rings), basic pointset topology (compactness, connectedness, metric spaces, quotient and subspace topplogies) and analysis. A review will be done at the beginning of the course.
 No knowledge of smooth manifolds, algebraic topology, differential forms or functional analysis is assumed, but it will be helpful to know its rudiments.
Learning Outcomes
On successful completion of this course, students will be able to:
1) Demonstrate an understanding of the basic theory of vector bundles
2) Demonstrate familiarity with a range of examples within this theory
3) Demonstrate an understanding of the definition of the Kgroups for a topological space
4) Apply Bott periodicity to compute some Ktheory groups
5) Formulate and prove an index theorem for Toeplitz operators
6) Apply the theory in the course to solve a variety of problems at an appropriate level of difficultyUniversity Graduate Attributes

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.

Assessment
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 Summary
Component Weighting Outcomes Assessed Assignments 30% All Exam 70% All Assessment Related Requirements
An aggregate score of at least 50% is required to pass the course.Assessment Detail
There will be a total of 6 homework assignments, due one week after they are assigned. Each will cover material from the lectures, and in addition, will sometimes go beyond that so that students may have to undertake some additional research.
Submission
Homework assignments must be given to the lecturer in person or emailed as a pdf file. Failure to meet the deadline without reasonable and verifiable excuse may result in a significant penalty for that assignment.
Course Grading
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 149 Fail P 5064 Pass C 6574 Credit D 7584 Distinction HD 85100 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.

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 ongoing 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.

Fraud Awareness
Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zerotolerance 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.
