Foreword.
Applications do not necessarily mean practical computations. In these notes, in particular, we can see some very useful applications of linear algebra
to ancient problems of construction by compasses and ruler and then to the problem
of solvability of algebraic equations by radicals.
In this lecture course we go straightforwardly to some famous results of algebra
in the hope that a concise and rigorous exposition may help to make difficult topics
more friendly and less difficult. The notes produce the whole picture of the course
and contain all basic steps and fundamental theorems. However, the proofs are not
in the notes and will be presented during the school.
Please be aware that next to none of the steps evolved in these notes is trivial.
So the proofs are essential part of the course. I hope we can enjoy them together as
the ideas and even details of the proofs are deep, ingenious and beautiful.
