McDougal Lecture in Mathematics: Dr. Jessica McDonald

McDougal Lecture in Mathematics; Dr. Jessica McDonald presents Beyond the Four Colour Theorem: Exploring Tutte's Flow Conjectures in Graph Theory.

W. T. Tutte made three conjectures about so-called flows in graphs between the 1950s and 1970s. These conjectures aim to generalize important theorems about colouring planar graphs, one of which is the famous Four Colour Theorem. In this lecture, we'll start with some graph basics, and talk about both colourings and flows in graphs. We'll discuss Tutte's Flow Conjectures and some mathematical history. We'll also discuss modern avenues of approach when working with flows in graphs, and I will highlight some of my joint work with others on flows, in particular Brewer-Castano, DeVos, Nurse, Pivotto, Rollova and Samal.
