Query: Bicategories of operator algebras and Poisson manifolds   It is well known that rings are the objects of a bicategory, whose arrows are
bimodules, composed through the bimodule tensor product. We give an analogous
bicategorical description of C*-algebras, von Neumann algebras, Lie groupoids,
symplectic groupoids, and Poisson manifolds. The upshot is that known
definitions of Morita equivalence for any of these cases amount to isomorphism
of objects in the pertinent bicategory.
