The study of number theory inevitably includes a knowledge of the
problems and techniques of elementary number theory, however the tools
which have evolved to address such problems and their generalizations
are both analytic and algebraic, and often intertwined in surprising
ways.

The candidate should be well-versed in the concepts, definitions,
examples, theorems and proofs in elementary, analytic, and algebraic
number theory, and demonstrate facility with the techniques in
either analytic or algebraic number theory.


The candidate should easily be able to give all relevant definitions,
provide standard examples, state major theorems, and provide the ideas
behind their proofs.  Specific topics which will be covered include:





\subsection*{Elementary Number Theory:}

\begin{compactenum}
