## A proof of the prime number theorem IV

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.

## Summing $\mu(n)$: a better elementary algorithm

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

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.
