The Skewes Number

Subject: the Skewes number \Xi, the least integer for which \pi(x), the number of primes up to x, exceeds li(x), the logarithmic integral of x. Theme: the explicit formula of Riemann. This is the thread which runs through the course. Novel aspects: Can you hear the Riemann Hypothesis? This is a unique self-contained text which contains the theory of the Skewes number, and also includes the numerical realm. Mostly undergraduate level, partly graduate level. Many exercises included.

This title has been published by the AMS as The Great Prime Number Race and is available at https://bookstore.ams.org/STML-92.
