Combinatorial k-systoles on a punctured torus and a pair of pants
Confluentes Mathematici, Volume 13 (2021) no. 2, pp. 29-38.

In this paper S denotes a surface homeomorphic to a punctured torus or a pair of pants. Our interest is the study of combinatorial k-systoles, that is closed curves with self-intersection numbers greater than k and with least combinatorial length. We show that the maximal intersection number I k c of combinatorial k-systoles of S grows like  k and lim sup k+(I k c -k)=+.

This result, in case of a pair of pants and a punctured torus, is a positive response to the combinatorial version of the Erlandsson-Parlier conjecture, originally formulated for the geometric length.
