Title of talk: Solved and unsolved problems in number theory

Abstract: I will survey a few of my favorite problems in number theory, such as Fermat's last theorem (solved) and the rectangular box problem (unsolved).

Title of talk: Hilbert's tenth problem

Abstract: Hilbert dreamed that someday we would have a general method for solving all diophantine equations, but in 1970 it was proved that no such method exists. By-products of the proof include connections to prime-producing polynomials and the Riemann hypothesis.

Title of talk: Undecidability everywhere

Abstract: Undecidable problems exist in many other subjects, such as group theory and topology. There are also a few problems in number theory and algebraic geometry whose decidability status is not yet known.
