In this (pro)seminar we will use the basics of linear algebra, analysis, number theory, and some elementary but omnipresent concepts and reasonings from discrete mathematics to understand some of the proofs that Paul Erdos would have qualified as "The proofs from THE BOOK". These proofs are supposed to be highly efficient, concise and beautiful in terms of techniques and scope.

Participants should feel comfortable with the contents of 'Linear algebra 1', and perhaps 'Linear algebra 2'. If there are interested students who have already done the 'Algebra und Zahlentheorie' module, we will also be able to find interesting topics for them.
