Infima of length functions and dual cube complexes

In the presence of certain topological conditions, we provide lower bounds for the infimum of the length function associated to a collection of curves on Teichm"uller space that depend on the dual cube complex associated to the collection, a concept due to Sageev. As an application of our bounds, we obtain estimates for the `longest’ curve with $k$ self-intersections, complementing work of Basmajian \cite{basmajian}.
