Formal Lagrangian Operad
Given a symplectic manifold M, we may define an operad structure on the the spaces Ok of the Lagrangian submanifolds of (M¯)k×M via symplectic reduction. If M is also a symplectic groupoid, then its multiplication space is an associative product in this operad. Following this idea, we provide a defo...

Given a symplectic manifold M, we may define an operad structure
on the the spaces Ok of the Lagrangian submanifolds of (M¯)k×M via
symplectic reduction. If M is also a symplectic groupoid, then its multiplication
space is an associative product in this operad. Following this idea, we provide
a deformation theory for symplectic groupoids analog to the deformation
theory of algebras. It turns out that the semiclassical part of Kontsevich's
deformation of C∞(ℝd) is a deformation of the trivial symplectic groupoid
structure of T∗ℝd. |
