# Gallian to deliver Pi Mu Epsilon Lecture

The 13th Annual Pi Mu Epsilon Lecture will be delivered by Joseph Gallian, the Morse Alumni Distinguished University Professor of Teaching in the Department of Mathematics and Statistics at the University of Minnesota Duluth.

The lecture will be 4 to 5 p.m. Oct. 11 in 115 Avery Hall. It will be preceded by a reception with refreshments at 3:30 p.m. in Avery 348.

In the talk, "Using Mathematics to Create Symmetry Patterns," Gallian will explain how to create symmetrical patterns using Hamiltonian paths, spanning trees, exponential functions, logarithms and modular arithmetic. These methods were used to create the image for the 2003 Mathematics Awareness Month poster.

Gallian has been a professor at the University of Minnesota Duluth since 1972. He has authored or edited six books and more than 100 articles. Between 1977 and 2019, Gallian ran 40 undergraduate research programs at Duluth.
