After successful completion of the course, students are able to
explain divisibility properties of integers and to deduce main properties like the Fudamental Theorem of Number Theory,
define and to apply number theoretic functions,
use and to apply congruences,
explain the theory of quadratic residues and to deduce their mein properties
formulate important properties of prime numbers, to apply them, and to sketch their proofs,
identfy several simple classes of Diophantine equation and to apply corresponding soltuion methods, and
to sketch the ideas and methods that are needed to proof the main theorems.
Divisibility, number-theoretic functions, congruences, quadratic residues, prime numbers, diophantine equations
