DESCRIPTION:Every contact 3-manifold is locally contactomorphic to the sta
 ndard contact R^3\, but this fact does not necessarily produce large chart
 s that cover the manifold efficiently. I&#39\;ll describe joint work with 
 Dave Gay and more recently\, Dan Mathews\, which uses an open&nbsp\; book 
 decomposition of a contact manifold to produce a particularly efficient co
 llection of such contactomorphisms\, together with simple combinatorial da
 ta describing how to reconstruct the contact 3-manifold from these charts.
 &nbsp\;&nbsp\; We use this construction to define&nbsp\; front projections
  for Legendrian knots and links in arbitrary contact 3-manifolds\, general
 ising existing constructions of front projections for Legendrian knots in 
 S^3 and universally tight lens spaces.  <br><br><br><br>
