Elementary number theory

7.5 credits

In this course we study properties of the integers without using tools from other mathematical diciplines as algebra and analysis. Divisability, prime numbers and congruences are fundamental concepts in the course. By using these we study properties of arithmetic functions, quadratic residues and primitive roots. In the course theory and applications are combined. Among the applications we find, cryptography, coding and random number generation.


Linnaeus University’s campus is located roughly 15 minutes with bicycle from the city centre. Campus is like a small society in its own right, with the university, student accommodation and student life all in one place. Everything happens on campus – here you become part of a creative knowledge environment and an eventful student life.

What will you find when exploring Växjö? There is a great selection of restaurants and cosy cafés. There is a large lake in the city centre, beautiful nature is always nearby. Many students enjoy the combination of the city centre in Växjö and life on campus. This is where your dream of the future begins!
