On contact mapping classes of prequantizations
arXiv (Cornell University)(2023)
Abstract
We present examples of prequantizations over integral symplectic manifolds which admit infinitely many smoothly trivial contact mapping classes. These contact mapping classes are given by the components of strict contactomorphisms which are lifted from the identity component of the symplectomorphism group of the base manifold. Along the way, we study the lifting problem of symplectomorphisms of the base manifold to strict contactomorphisms of the prequantization.
