Main Assessment In: April/May
The main topics will include review of basic material on congruences, Fermat's Little Theorem and Euler's Theorem, quadratic reciprocity, continued fractions and Pell's equation, a basic introduction to algebraic number theory including quadratic and cyclotomic number fields, rings of integers, factorisation theory and diophantine problems, arithmetic functions, introduction to analytic number theory including asymptotic estimates for the distribution of primes and the relationship of these topics with the Riemann Zeta function and the Riemann Hypothesis.
Intended Learning Outcomes of Course
By the end of this course students will be able to:
a) solve congruence problems using results from the course;
b) use continued fractions to find solutions to Pell's equation;
c) exploit the algebraic structure of quadratic number fields and cyclotomic fields to solve Diophantine problems;
d) work with arithmetic functions using convolution and Möbius inversion;
e) state the Prime Number Theorem and deduce basic results from it.;
f) recall results on general number fields and their rings of integers, including cyclotomic fields.
Minimum Requirement for Award of Credits
Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
