Vanishing of higher Legendrian homology for rainbow closures

math.SGarXiv:2608.24844

Abstract

We show that the higher Legendrian homology of any Legendrian link given by the rainbow closure of a positive braid must necessarily vanish. The result is proven in the most general setting: for any number of strands and crossings, integrally and with one basepoint per component of the Legendrian link.
