Abstract
We show that the Golod property of a Stanley-Reisner ring can depend on the characteristic of the base field. More precisely, for every finite set of prime numbers we construct simplicial complexes and , such that is Golod exactly in the characteristics in and is Golod exactly in the characteristics not in . Along the way, we show that a one-dimensional simplicial complex is Golod if and only if it is chordal.
