"Lonely runners in function fields"
Abstract. The lonely runner conjecture (1967) asserts that if m
runners with distinct constant speeds run around a unit circle
starting at a common time and place, then each runner will at some
time be separated by a distance of at least 1/m from the others.
We formulate the conjecture in a function field setting, and
obtain some partial results. We interpret the question as a
covering problem involving partial circulant matrices, and analyse
the extremal problem using a combinatorial structure known as a
sunflower. Joint with Luka Rimanić.
