I'm in the process of preparing next week's Chapter 2, on the Langlands program and the landscape of different kinds of L-functions. Most research talks on the Langlands program are incomprehensible unless you already have huge amounts of technical background. But I have found one short
The logarithmic integral function $\mathrm{li}(x)$ is defined as \[ \mathrm{li}(x) = \int_0^{\infty} \frac{\mathrm{d}t}{\log(t)} \] where $\log$ is is the natural logarithm, and the integral is understood as the Cauchy principal value at $t=1$. The function $\mathrm{li}(x)$ is for $x&
The Riemann Hypothesis may be the greatest unsolved math problem of all time. In his book Zeta and L-functions of varieties and motives, Bruno Kahn calls it an unapproachable mystery. In a short YouTube clip, Terence Tao likened it to climbing a sheer cliff face, a mile high, with no
For obvious reasons, it is hard to find very accessible introductions to L-functions. Here are three pieces of exposition where such an introduction is attempted. Perhaps you will find them interesting! And perhaps you can send them to your uncle in order to explain why you love L-functions. 1: A
Part of the philosophy I hope to promote at PeakMath is to play! Play around with the mathematical entities you encounter! Try silly things, make fun observations, and don't worry too much about whether your findings are "important" or not. In an interesting philosophical paper, Alexandra
In June 2018 a conference was held in Bristol called Perspectives on the Riemann Hypothesis. The talks from this conference are not on YouTube, but can be found on the conference webpage. Many of these talks are excellent, but today I specifically want to recommend the talk by Sarnak, called
On this very day, May 6th, exactly 5! years have passed since the birth of André Weil. One of the truly great mathematical minds of the 20th century, Weil proposed his famous Weil Conjectures on the structural properties of local zeta functions. They were eventually resolved by himself in the
Imagine that one day, as you go about your daily business, you are suddenly abducted by aliens, quite unexpectedly. You are told by the captain of the alien spaceship that you will be executed 24 hours from now, unless by that time you have provided them with a prime number
Peter Sarnak of Princeton University is one of the world's leading experts on the Riemann Hypothesis. Last week a very nice talk was posted on the Harvard CMSA YouTube channel, where Sarnak reviews what is known about the Generalized Riemann Hypothesis and various approaches that have been tried.
If you are planning to follow the RH Saga course notes, and you need to brush up on complex analysis, here are some really nice lecture notes by Dan Romik. The chapters are brief, and chapter 15 covers all the basic properties of the Riemann zeta function. These lectures notes
This should create the prime number waves from the zeroes of the Riemann zeta function. Increase the number \(n\) for more pronounced prime number peaks:
The equation \( \sum_{k} \frac{1}{k^2} = \frac{\pi^2}{6} \) should render inline, and this should render as display: \[ \sum_k k = - \frac{1}{12} \] Is this working? Testing the align environment: \[ \begin{align} \zeta(s) &= 0 \\ s &\notin \mathbb{R} \end{align} \]

This is the beginning of a new PeakMath site. We are currently in the process of testing and setting things up, and will officially launch on May 6th at peakmath.org. Welcome back in May!
