It is proved that for each compact (bordered) surface 7 and each integer k there is a constant N with the following property: If 1 is a family of pairwise nonhomotopic closed curves on 7 such that any two curves from 1 intersect in at most k points, then 1 contains at most N curves.

## Abstract We study coherent systems on an irreducible nodal curve of arithmetic genus 1. We determine conditions for their nonβemptiness and study properties like irreducibility, smoothness, seminormality and rationality.
