Title:  Cluster varieties from Legendrian knots

Abstract:   I will describe how the Postnikov / Fock-Goncharov theory
cluster structures, boundary measurement map, etc. naturally emerge
from the sheaf-theoretic encoding of Floer-theoretic structures
associated to Lagrangian fillings of Legendrian knots. Time
permitting, I will also explain a geometric framework in which there
is a representative for the cluster chart appearing "on the other side
of the square move". No knowledge of sheaf or floer theory is
presumed. This talk presents joint work with David Treumann, Harold
Williams, and Eric Zaslow.
