The prime number theorem asserts that the $n$-th largest prime has approximate size $n \log n$.
We shall give the proof of Iwaniec in his recent AMS book on the Riemann zeta function.
These lectures are at the level of beginning graduate students.

Joint with Lola Thompson.

Consider either of two related problems: determining the precise
number $\pi(x)$ of prime numbers $p\leq x$, and computing the Mertens
function $M(x) = \sum_{n\leq x} \mu(n)$, where $\mu$ is the Möbius function.

The two best algorithms known are the following:

## Locally harmonic Maass forms and central $L$-values

Location:
MPIM Lecture Hall

In this talk, we will discuss a relatively new modular-type object known as
a locally harmonic Maass form.
We will discuss recent joint work with Ehlen, Guerzhoy, and Kane with
applications to the theory of $L$-functions. In particular, we find
finite formulas for certain twisted central $L$-values of a family of
elliptic curves in terms of finite sums over canonical binary quadratic
forms. Applications to the congruent number problem will be given.

## On Maeda's Conjecture

In 1997 Maeda established a conjecture in his work with Hida
that has been popularized in the following form:
the characteristic polynomials of the Hecke operators  acting on the
space of cusp forms of fixed weight for SL(2,Z) are all irreducible and
have full Galois group. Beyond Maeda-Hida's work, this conjecture, if
true, would have different consequences; for example for the
non-vanishing of L-functions or the inverse Galois problem. We will
explain the significance of the conjecture and discuss some recent
progress.
