The Exceptional Character Issues

Abstract: Among the Dirichlet characters there is at most one which resists to obey the rules of classical theory of L-functions. If you believe in the validity of the Grand Riemann Hypothesis then there is no issue. I will try to convince that it would be better for the theory of
prime numbers that this illusory character does exist!

Professor Henryk Iwaniec, New Jersey Professor of Mathematics at Rutgers University, is a famous Number theorist, originally from Poland. He is a recipient of the Cole Prize in Number theory and the Ostrowski Prize. His many striking results include the proof of the infinitude of primes of the form a^2 + b^4 , proved jointly with John Friedlander; such a result was totally unexpected, since the main technique of sieve theory cannot usually distinguish between primes and products of two primes. Iwaniec is also an excellent expositor of Mathematics, and for his books he received the 2011 Steele Prize for exposition from the American Mathematical Society.

The Leonidas Alaoglu Memorial Lecture was established by friends and family of the late Leonidas Alaoglu in recognition of his great talents, distinguished contributions to mathematics, and long friendship with Caltech. The Institute is privileged to honor his memory with a lecture each year by an outstanding mathematician.
