Abstract: | Let }L
t{,t ∈ 0, 1], be a path of exact Lagrangian submanifolds in an exact symplectic manifold that is convex at infinity and of dimension
≥6. Under some homotopy conditions, an engulfing problem is solved: the given path }L
t{ is conjugate to a path of exact submanifolds inT
*Lo. This impliesL
t must intersectL
o at as many points as known by the generating function theory. Our Engulfing theorem depends deeply on a new flexibility property
of symplectic structures which is stated in the first part of this work.
