This thesis will deal with algebraic extensions. The
goal is to give the reader an introduction to algebraic extensions,
euclidian domains, unique factorization domains as well as more
specic theories for example how to nd primes in the gaussian
integers. The layout of the report will be to start with the more
general theories and as we progress narrow down on more specic
theories. It is assumed that the reader already is familiar with
some basic algebra.
The rst two chapters will introduce the reader to algebraic ex-
tensions and some more general denitions of primes and other
properties. The next three chapters will cover some more speci-
k properties of rings such as unique factorization. In the last
three chapters we will move on to investigate more specik exten-
sions starting with quadratic extensions and then moving on to
the gaussian integers as well as introducing the reader to some un-
solved problems in the nal chapter.
Throughout this whole thesis there will be a lot of examples where
an example following a denition or theorem will try to illustrate
that particular concept.
