Small filling sets of curves on a surface

Abstract:
We show that the asymptotic growth rate for the minimal cardinality of a set of simple closed curves on a closed surface of genus g which fill and pairwise intersect at most K≥1 times is 2√g / √K as g→ ∞. We then bound from below the cardinality of a filling set of systoles by g / log(g). This illustrates that the topological condition that a set of curves pairwise intersect at most once is quite far from the geometric condition that such a set of curves can arise as systoles.
