Suppose B=F[x,y,z]/h is the homogeneous coordinate ring of a characteristic p degree 3 irreducible plane curve C with a node. Let J be a homogeneous (x,y,z)-primary ideal and n→enbe the Hilbert–Kunz function of B with respect to J. Let q=pn. When J=(x,y,z), it is known that en=73q2−13q−R where R=53 if q≡2(3), and is 1 otherwise. We generalize this, showing that en=μq2+αq−R where R only depends on qmod3. We describe α and R in terms of classification data for a vector bundle on C.
