Alaoglu Memorial Lecture 4:15 p.m. 151 Sloan
Henryk Iwaniec
The Exceptional Character Issues Abstract: Among
the Dirichlet characters there is at most one which resists to obey the
rules of classical theory of Lfunctions. 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 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.
