"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.
