We present regular seminars on a range of pure mathematics interests. Students, staff and visitors to UQ are welcome to attend, and to suggest speakers and topics.

Seminars are usually held on Tuesdays from 2 to 3pm.

Talks comprise 45 minutes of speaking time plus five minutes for questions and discussion.

Information for speakers

Researchers in all pure mathematics fields attend our seminars, so please aim your presentation at a general mathematical audience.

Oscillations of the Prime Number Theorem Error Term

14 May 2019 3:00pm4:00pm
A commonly known version of the prime number theorem is that the prime number counting function pi(x) grows like x/log(x). An equivalent statement is that the Chebyshev Psi function Psi(x) grows like x. It goes back to Littlewood that the error term Psi(x) - x changes sign infinitely many times. We refine a method of Kaczorowski to give a lower bound on the number of sign changes in Psi(x) - x.
