Query: Reducing almost Lagrangian structures and almost CR geometries to
  partially integrable structures   This paper demostrates a method for analysing almost CR geometries $(H,J)$,
by uniquley defining a partially integrable structure $(H,K)$ from the same
data. Thus two almost CR geometries $(H,J)$ and $(H',J')$ are equivalent if and
and only if they generate isomorphic induced partially integrable CR geometries
$(H,K)$ and $(H',K')$, and if the set of CR morphisms between these spaces
contains an element that maps $J$ to $J'$. Similar results hold for almost
Lagrangian structures.
