# MATHS 714 : Number Theory

## Science

### Course Prescription

A broad introduction to various aspects of elementary, algebraic and computational number theory and its applications, including primality testing and cryptography.

### Course Overview

Number theory is one of the oldest and most beautiful branches of mathematics. It concerns problems involving prime numbers and Diophantine equations, and includes many of the most famous problems in mathematics such as Fermat's last theorem and the Goldbach conjecture. Number theory continues to be a dynamic research area with numerous connections with other branches of mathematics as well as applications in the real-world (such as public key cryptography). The course builds on undergraduate knowledge in pure mathematics (especially abstract algebra, as seen in MATHS 320 and MATHS 328). The course gives an overview of basic methods and results in number theory.

### Course Requirements

Prerequisite: B+ in MATHS 328 or 320

### Capabilities Developed in this Course

 Capability 1: Disciplinary Knowledge and Practice Capability 2: Critical Thinking Capability 3: Solution Seeking Capability 4: Communication and Engagement Capability 5: Independence and Integrity

### Learning Outcomes

By the end of this course, students will be able to:
1. Use and apply the definitions and tools of number theory, and ability to solve challenging theoretical problems in number theory (Capability 1, 2 and 3)
2. Be able to write clear and precise proofs and to communicate effectively in written form (Capability 4 and 5)
3. Compute with linear congruences, use the Chinese Remainder Theorem, compute with primitive roots and multiplicative functions, and prove existence of primitive roots modulo p (Capability 1)
4. Understand and use Legendre symbols and prove the quadratic reciprocity law (Capability 1 and 3)
5. Demonstrate an understanding of Dirichlet's theorem, and ability to prove infinitely many primes in residue classes in some special cases (Capability 1 and 4)
6. Compute continued fractions and solve Pell-type equations (Capability 1 and 3)
7. Demonstrate an understanding of algebraic number theory and certain classes of Diophantine equations (such as elliptic curves) (Capability 1, 2, 3, 4 and 5)

### Special Requirements

Must sit exam

This course is a standard 15 point course and students are expected to spend 10 hours per week involved in each 15 point course that they are enrolled in.

For this course, you can expect 3 hours of lectures, 4 hours of reading and thinking about the content and 3 hours of work on assignments and/or test preparation.

### Delivery Mode

#### Campus Experience

Attendance is expected at lectures.
Lectures will be available as recordings.
The course will not include live online events.
Attendance on campus is required for the exam.
The activities for the course are scheduled as a standard weekly timetable.

### Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

### Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.

### Class Representatives

The content and delivery of content in this course are protected by copyright. Material belonging to others may have been used in this course and copied by and solely for the educational purposes of the University under license.

You may copy the course content for the purposes of private study or research, but you may not upload onto any third party site, make a further copy or sell, alter or further reproduce or distribute any part of the course content to another person.

### Inclusive Learning

All students are asked to discuss any impairment related requirements privately, face to face and/or in written form with the course coordinator, lecturer or tutor.

Student Disability Services also provides support for students with a wide range of impairments, both visible and invisible, to succeed and excel at the University. For more information and contact details, please visit the Student Disability Services’ website

### Special Circumstances

If your ability to complete assessed coursework is affected by illness or other personal circumstances outside of your control, contact a member of teaching staff as soon as possible before the assessment is due.

If your personal circumstances significantly affect your performance, or preparation, for an exam or eligible written test, refer to the University’s aegrotat or compassionate consideration page .

This should be done as soon as possible and no later than seven days after the affected test or exam date.

### Learning Continuity

In the event of an unexpected disruption, we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and course assessment continues to meet the principles of the University’s assessment policy. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator/director, and if disruption occurs you should refer to the university website for information about how to proceed.

The delivery mode may change depending on COVID restrictions. Any changes will be communicated through Canvas.

### Student Charter and Responsibilities

The Student Charter assumes and acknowledges that students are active participants in the learning process and that they have responsibilities to the institution and the international community of scholars. The University expects that students will act at all times in a way that demonstrates respect for the rights of other students and staff so that the learning environment is both safe and productive.
