An Introduction to Elementary Set Theory Guram Bezhanishvili and Eachan Landreth 1 Introduction In this project we will learn elementary set theory from the original historical sources by two key gures in the development of set theory, Georg Cantor (1845{1918) and Richard Dedekind (1831{1916). We have to introduce the algebra of formal power series in order to vindicate what Euler did with great tact and insight. What are the \objects" of number theory analogous to the above description? 5 Indirect Argument: Contradiction and Contraposition The point of departure for a proof by contradiction is the supposition that the statement to be proved is false. Because the fundamentals of Set Theory are known to all mathemati-cians, basic problems in the subject seem elementary.
