## William Kirwin## Complex-time flows in geometric quantizationUsing ideas of Thiemann, the adapted complex structure on a tubular neighborhood of a real-analytic Riemannian manifold in its tangent bundle can be understood as the ``time-i'' geodesic flow. On the tangent bundle of a compact Lie group, the geometric quantization of this flow composed with the Schroedinger quantization of the associated Hamiltonian is Hall's coherent state transform (CST), a unitary isomorphism relating square-integrable functions on the group to certain holomorphic functions on the complexification. In this talk, I will explain these ideas, and how they may be generalized to yield an infinite-dimensional family of ``complex-time'' flows, each of which generates a generalized CST. |
