In this project we will study some aspects of Lie theory and some of its interactions with symplectic geometry. In particular we will investigate under which assumptions a connected Lie group G acting on a connected symplectic manifold (M,É) via symplectomorphisms, admits a central extensions G2 acting as a group of symmetries of a pair (L,±) of a principal R/D-bundle, where D is a discrete subgroup of the reals, and ± is a connection one-form on L whose curvature is the pull-back of É via the canonical projection p : L ’ M. We will see how this problem is strictly related to the problem of pre-quantizing the classical phase-space (M, É) and to the problem of the existence of the central extension of the Lie group G integrating a central extension of the corresponding Lie algebra g.
