Graduate Seminar in Number Theory
Tel Aviv, Spring 2005
Zeev Rudnick
Schedule
Tueday 14-16, Schreiber 8
The seminar will discuss topics in "analytic" number theory.
It will consist mostly of presentations by the students.
Possible Topics:
-
Arithmetic functions and function field arithmetic
- Arithmetic functions, Dirichlet convolution, Moebius inversion
- The Prime Number Theorem for Fq[x].
-
Binary quadratic forms
- binary quadratic forms, the modular group, reduction theory,
the class number.
- Unique factorization in imaginary quadratic fields.
- Dirichlet's class number formula.
-
Primes in arithmetic progression
- Dirichlet characters, orthogonality relations;
Dirichlet L-functions, analytic continuation to Re(s)>0.
- Infinite products and the Euler product for ζ(s)
and L(s, χ ).
- Primes in arithmetic progressions and the connection to L(1, χ ).
-
Sieve methods
- The sieve of Erathosthenes
- Selberg's upper bound sieve
- Applications: An upper bound for the number of twin primes up to x.
-
The zeros of Riemann's zeta function
-
The Gamma function and its properties, Stirling's formula.
- The Fourier transform and Poisson summation.
- The Riemann zeta function: analytic continuation and functional
equation.
- Entire functions of finite order and Weierstrass products
- The zeros of ζ(s)- basics.
- The asymptotic formula for N(T),
the number of zeros up to height T.
- Relating zeros and primes: Riemann's explicit formula
- The prime number theorem - an overview
