Exotic automorphisms of the Lie algebra of polyvector fields


Sergei Merkulov

(Stockholm)

Abstract: Using a new compactification of the (braid) configuration space of n points in the upper half plane we construct a family of exotic Lie-infinity automorphisms of the Schouten algebra of polyvector fields on an affine space depending on a Kontsevich type propagator.
