Legendrian Barriers

In a previous work with Felix Schlenk, we showed that an analogue of the phenomenon of Lagrangian barriers holds in the contact framework in $S^3$ : there exist (explicit) Legendrian complexes of arcs in $S^3$ that have short Reeb chords to many Legendrian loops. The aim of this talk is to explain that this phenomenon holds more generally in any prequantization bundle (of arbitrary dimension).
